Overview

The HTB-1 High Tensile Brass Copper Alloy BU-499 4851435 Bush Sleeves SAE430B Sliding Bearings belongs to our Bearing range and is stocked for same-day wholesale dispatch. Buyers choose this bearing for its bronzecopper(cusn12, c93200, sae660) build . Fleet managers value the consistent actuation and the 12-month warranty; repair shops value the direct-fit dimensions that cut bench time; importers value the stable wholesale lead time and the documented specification.

What you read here is the same specification our bench checks against: figures are measured, recorded, and published as-is, and any value the line has not verified is simply left blank. That is the standard the whole Bearing range is held to.

Technical specification

Supplied brand: Vidishi Auto — not PVB-branded; the original maker is referenced for fitment cross-checks only.

Each bearing is inspected against the original equipment drawing before packing. The bronzecopper(cusn12, c93200, sae660) body resists wear under continuous duty and holds tolerance through thermal cycling. The electrical rating is validated across the temperature range. Dimensions are per the OE drawing. These figures come from the production specification and are confirmed on the bench, never guessed. Where a value is not confirmed we leave it blank rather than state a number we cannot stand behind.

Packing includes the mating connector and the sealing items pictured in the gallery; nothing extra needs to be sourced before the install. Torque values and clearances follow the original equipment spec.

The Material of BronzeCopper(CuSn12, C93200, SAE660) matters because it decides wear life and resistance to the medium.

The Certification of ISO 9001:2015；IATF 16949:2016 matters because it shows the compliance the unit can be documented against.

Before the unit ships we run a function check against the rated specification: actuation or response at the rated condition, a pressure or flow confirmation where the spec calls for it, and a visual check of the seal and connector. The result is either a pass stamped on the carton or the unit is pulled. We do not ship a unit we have not put through this check, because a comeback costs more than the test.

Fitment

Fitment verification

Confirm the engine code plate and the part number BU-499, 4851435 before purchase. This bearing fits 、、spring、etc. Reference model: JDB-1U. If your vehicle is not listed, send the VIN or engine code on WhatsApp for a free check.

The fastest fitment check is visual: same stamping, same connector, same bolt pattern. If any of the three disagrees, stop and send us a photo — forcing a wrong revision in damages more than the part itself.

Typical replacement scenarios

In every scenario the first step is identical — confirm BU-499, 4851435 against the old stamping before the wrench moves.

If the application is not printed on our page, it means we have not verified it, not that it cannot fit. Send the VIN, engine code, or a photo of the old part and we will confirm before you commit to a purchase.

Symptoms & engineering notes

Engineering notes

The HTB-1 High Tensile Brass Copper Alloy BU-499 4851435 Bush Sleeves SAE430B Sliding Bearings is designed around the original equipment geometry so the bearing seats without modification. The bronzecopper(cusn12, c93200, sae660) element keeps tolerance under thermal cycling and vibration. Actuation stays consistent across the rated temperature range. The pressure path is validated on the test bench. Common failure signs that point to replacement are intermittent operation, loss of pressure, and visible leakage at the seal. Replace on a clean bench and torque to the OE spec. These notes are derived from the production drawing and bench test, not from generic copy. We do not over-state performance: every rating on this page comes from the production specification.

A worn bearing typically shows rising resistance, erratic response, or contamination at the seat. Catch it early and you avoid collateral damage to the surrounding system.

Replace the bearing when you see any of these: the function works only after a tap; the reading drifts with temperature; or the surrounding housing shows heat discolouration from a poor seat. Catching it early protects the more expensive parts downstream. After fitting, a five-minute functional test saves a comeback.

No figure on this page was borrowed from a competitor catalogue. If the line has not verified a value, the field stays blank — professional buyers can audit every number we publish.

Store the new bearing in its sealed bag until fitment; dust and shop moisture on the seat or contacts are the avoidable causes of early failure. Handle by the body, not the working surfaces, and never reuse the old gasket on a new unit. A clean, dry fit is most of the battle for a long service life.

Verified details from supplier and reference listings: HTB-1 high tensile brass bushes are made from CuZn25Al5Mn4Fe3 manganese bronze, also known as SAE 430B or C86300, with tensile strength above 750 MPa.. JDB-1U oil-groove bushings use a CuZn25Al6Fe3Mn3 base with hardness of HB 210 to 270, roughly double that of standard tin bronze sleeves.. The solid lubricant embedded in the bronze transfers to the shaft through friction heat, forming a lubrication film that makes the bushing maintenance free.. SAE 660 (C93200) cast bronze contains about 83 percent copper, 7 percent tin, 7 percent lead and 3 percent zinc, giving good anti-friction performance.. These flanged and cylindrical bushings are widely used in excavator joints, cranes, agricultural machinery, mining equipment and large gearbox bores.. Maximum working PV for this bushing class is around 10 MPa·m/s, with a maximum allowable load of 100 N/mm² for slow-speed heavy-load pivots..

Installation

1. Disconnect power and relieve system pressure.
2. Remove the old bearing after noting the part number BU-499, 4851435.
3. Clean the seat and check for debris or worn seals.
4. Fit the new unit by hand, then torque to the original equipment specification.
5. Restore power, pressurise slowly, and inspect for leaks.
6. Run a functional test before returning the vehicle to service.

Installation difficulty is moderate. If unsure, use a qualified technician. Keep the old part until you confirm the new unit behaves correctly.

Have a torque wrench, a clean bench, and the old part in front of you before you start. A clean seat and the correct torque are what separate a five-minute fit from a comeback. If the old unit shows heat or contamination, fix that root cause or the new bearing will fail the same way.

Bearing fit & clearance

Bearings live or die by the shaft and housing fit. Confirm the bore tolerance and the clearance class before pressing. This unit is a bronzecopper(cusn12, c93200, sae660)-steel bearing. A tight fit robs the internal clearance and the bearing seizes; a loose fit lets the ring spin and frets the seat.

• Measure the shaft and housing bore with a micrometer.
• Match the clearance class (C3/C4) to the application.
• Press on the ring that carries the interference fit.
• Never let the rolling force travel through the balls.

Clearance class is the number buyers overlook. C3 gives extra internal clearance for hot or interference-fit mounts, and railway and vibrating-screen housings usually call for it. Measure the seat before you order the fit, not after the bearing is pressed.

Sealing & lubrication

Sealed bearings ship with the grease charge set at the factory; relubrication is for open types only. Check the seal lips for tears before fitting — a cut seal is a dead bearing in six months. Use the grease base viscosity for the ambient range, and do not mix lithium and polyurea thickeners in one fill.

Grease is a seal, a coolant, and a noise damper in one. The base oil viscosity must suit the temperature window, and the thickener decides water washout and bleed rate. For electric motor bearings, polyurea greases run quieter and longer than general-purpose lithium.

Load rating & mounting

Match the dynamic and static load ratings to the application, not just the bore size. Heavy-load positions call for the bearing rating with margin. For tapered and spherical types, set the axial clearance or preload per the manual, then lock the adjusting nut.

Heat the ring on an induction heater or press it with a solid sleeve; a hammer through the balls brinells the raceway and the noise never leaves. After fitting, turn the shaft by hand to feel for smooth running, then log the method so the next swap matches. Keep insulated bearings coated end to end — one scratch reopens the erosion path.
