DZ911210015 Release Bearing 430 mm Assembly

DZ911210015 is an exclusive release bearing assembly for 430mm clutches, suitable for heavy-duty truck manual transmission systems and serving as the core transmission component of the clutch control mechanism. Its primary function is to bear the driving force from the release fork and accurately transmit it to the clutch diaphragm spring, realizing smooth engagement and disengagement of the clutch, reducing mechanical impact during gear shifting, and ensuring continuous power transmission. Adaptable to complex working conditions such as long-haul trunk transportation, mining heavy loads, and mountain climbing, the product can withstand extreme temperature differences and high-frequency operations, avoiding risks like disengagement jamming and power interruption, and improving shifting smoothness and driving safety.

Core Materials

The bearing outer ring is made of high-carbon chromium bearing steel with reinforced raceways; the balls are precision bearing steel with excellent wear resistance; the cage is integrally formed by stamped steel plate, featuring high toughness and resistance to deformation; the seals are oil-resistant nitrile rubber double sealing rings, preventing grease leakage and impurity intrusion; the circlip is made of 65Mn spring steel with long-lasting elasticity to ensure installation firmness.

Surface Treatment

The outer ring surface undergoes phosphating anti-rust treatment, with salt spray corrosion resistance of over 72 hours; the raceways adopt laser quenching technology, increasing hardness to HRC60-64, and wear resistance is improved by 40% compared with ordinary quenching; the mounting surface is polished to reduce installation friction and fit clearance.

Production Process

Precision raceway grinding is adopted to ensure smooth ball operation; the whole assembly undergoes dynamic and static balance calibration to avoid vibration during high-speed operation; high-temperature grease is pre-injected to meet the requirements of -40℃~120℃ wide-temperature working conditions; automatic press-fitting equipment is used for assembly, achieving 100% correct circlip installation. Each unit undergoes idle test, sealing performance test, and release stroke verification one by one before leaving the factory.

Quality System: Certified by both IATF16949 automotive industry quality system and ISO9001 general quality system

Batch Tracking: Each product is marked with batch number and production date by laser coding, production records are kept for 3 years, supporting full-batch quality traceability

Average Service Life: ≥5 years (or 400,000 kilometers, corresponding to the normal wear cycle of clutch friction plates)

Performance Improvement: The double sealing ring design effectively prevents grease leakage, extending service life by 50% compared with ordinary single-seal products; laser-quenched raceways reduce wear and shifting resistance, making engagement and disengagement smoother; pre-injected high-temperature grease requires no intermediate replenishment, with a long maintenance-free cycle; the quick-clamping circlip structure simplifies the replacement process and improves maintenance efficiency.

Harsh Environment Adaptation: It can withstand -40℃ low temperature in northern regions without jamming, and the grease does not solidify; adapts to 120℃ high-temperature working conditions in southern regions, with no seal aging or grease loss; in northwest desert and coastal saline-alkali environments, it has excellent anti-rust and anti-corrosion performance, avoiding operation failures caused by sand entering raceways or component rust.

Common Fault Improvement

Targeted solutions to common problems of original release bearings, such as idle noise, disengagement jamming, seal aging and oil leakage, circlip elastic attenuation, and excessive raceway wear. By strengthening materials and optimizing the sealing structure, it fundamentally solves the vulnerable common faults under high-frequency shifting conditions.

Maintenance Value

Relying on the quick-clamping circlip design, it can be disassembled and replaced independently without disassembling the clutch and flywheel assembly, reducing maintenance time by 60% compared with traditional integrated structures; its ultra-long service life matches that of clutch friction plates, reducing replacement frequency; stable disengagement performance can protect the diaphragm spring and release fork, lowering the overall maintenance cost of the clutch control system.

Packaging Configuration

Adopting three-layer protective packaging: inner layer wrapped with plastic film (preventing grease contamination) + middle layer of pearl cotton for anti-collision buffering + outer layer of hard carton. Moisture-proof desiccants are placed inside, and both ends of the bearing are sealed with special protective covers to avoid collision, dust intrusion, and moisture during transportation.

Installation Requirements

Check the bearing idle state before assembly to ensure no noise or jamming; apply a small amount of grease on the mounting surface to reduce fit friction; press the circlip evenly into the slot and verify elasticity with tools to prevent falling off; ensure no impurities at the contact with the release fork to avoid noise during operation.

Regular Inspection

Every 20,000 kilometers driven, check whether the bearing has noise and whether disengagement is smooth; every 100,000 kilometers, check the circlip elasticity and seal condition in conjunction with clutch maintenance, and handle leakage and noise in a timely manner.

Storage Requirements

Store in a dry and ventilated warehouse, avoid contact with oil, acid, and alkali substances, and keep away from high-temperature and humid environments; avoid extrusion during stacking to prevent bearing deformation and circlip failure; the shelf life of unopened products is 1 year, and they must be installed and used immediately after opening.

Replacement Tips

When problems such as shifting noise, incomplete disengagement, and engagement jitter occur, the release bearing must be inspected in a timely manner; priority should be given to same-spec OE number products during replacement to avoid damaging the clutch diaphragm spring due to mismatching.
