DG2776-2SH Double Rubber Sealed One-Way Sprag Clutch Bearing

DG2776-2SH upgraded sealed one-way sprag clutch bearing, equivalent base model DC2776, dimension 27.762mm inner bore × 44.422mm outer diameter × 13.5mm width. Suffix 2SH stands for double-side reinforced NBR rubber contact seals, effectively block gearbox metal debris and oil leakage. It adopts precision sprag wedge structure, realizes unidirectional torque transmission and overrunning free rotation, matched stamped steel retainer and standard clearance. Operates stably under frequent shifting impact and high-temperature gear oil environment inside auto transmission. Made of fully quenched high-purity GCr15 chrome bearing steel with strict dimensional tolerance, fully interchangeable with original OEM DG2776-2SH. Complete formal quotation will be provided within 24 hours upon inquiry.

• Double SH multi-lip oil-resistant rubber seals, anti-swelling under long-term gear oil immersion, stop impurity ingress and oil seepage, extend service cycle greatly

Q1: What does suffix 2SH mean on DG2776-2SH?
A1: 2SH represents double-side reinforced multi-lip rubber contact seals, comparing open DC2776, it adds dust-proof and anti-leakage sealing performance.

Q2: What is the function of sprag one-way clutch bearing?
A2: It realizes unidirectional torque transmission; when rotation direction reverses, sprag separates to achieve free overrunning, core component for automatic gearbox shifting control.

Q3: Can DG2776-2SH replace original DC2776 open type directly?
A3: Yes, inner bore, outer diameter and width dimensions are fully consistent; sealed version can be used as upgraded replacement for open model.
