RCT2850-1RUBS Automotive Clutch Release Bearing / RCT2850-1RU8S Angular Contact Ball Bearing

1.Product Overview

RCT2850-1RUBS and RCT2850-1RU8S are standard automotive hydraulic clutch release throwout bearings with unified boundary dimension d=28mm inner bore, D=50mm outer diameter, overall total thickness T=14.5mm, interchangeable with OEM part number 09269-28001 & VKC3529.

This RCT series integrates angular contact ball core with integrated plastic housing, specially designed for hydraulic clutch separation systems of compact passenger cars. Two suffix variants differ in sealing configuration to match different vehicle operating environments:

• RCT2850-1RUBS: Standard single-lip reinforced NBR contact rubber seal, universal version for general urban road clean & moderate dust driving conditions;
• RCT2850-1RU8S: Upgraded thickened multi-lip dust & mud-proof composite seal, enhanced anti-leakage and anti-grime performance for rural, construction site and muddy harsh road environments.

Inner/outer rings and steel balls adopt GCr15 chrome bearing steel with overall quenching and ultra-precision raceway grinding, low-friction long-life internal grease pre-filled at factory. Integrated nylon housing has excellent shock absorption and self-aligning ability to compensate minor assembly misalignment during clutch separation movement. Widely matched for small-displacement compact cars, mini sedans and light passenger vehicle clutch overhaul replacement.

3.Key Advantages

1. Integrated one-piece plastic housing + steel ball bearing core integrated molding, perfect matching hydraulic clutch fork structure, no extra spacer needed for direct vehicle replacement
2. Two sealing grades (RUBS standard / RU8S heavy mud-proof) cover full vehicle usage scenarios, flexible selection according to customer regional road conditions
3. GCr15 quenched steel raceway and uniform steel ball layout, smooth clutch pedal separation feel, low running noise without jitter during frequent gear shifting
4. Factory pre-filled special automotive long-life lithium grease, stable lubrication under high-temperature engine compartment environment, avoid early dry grinding ablation failure
5. Self-aligning plastic housing structure automatically absorbs assembly deviation between separation fork and bearing, reduce abnormal unilateral wear
6. Customizable options: Low-temperature cold-resistant grease, OEM laser marking, reinforced wear-resistant housing upgrade, customized outer packaging for auto parts distributors

Effectively reduce vehicle clutch separation noise and extend overhaul cycle for compact passenger cars
