YET204 Eccentric Lock Take-Up Insert Bearing 20mm Bore Double Lip Sealed Relubricatable Bearing

YET204 is wide inner ring spherical outer insert bearing with eccentric locking collar, inner bore size 20mm, specially matched for take-up bearing housings. It features DD double lip contact rubber seals on both sides and side grease nipple for regular relubrication.
Spherical outer ring provides ±3° self-aligning compensation to offset shaft deflection and housing machining errors during assembly. Widened inner ring integrated with one-piece eccentric lock collar, the eccentric cam tightly clamps transmission shaft to prevent inner ring slipping under long-term continuous vibration of conveyors and agricultural equipment. Internal deep groove ball structure can bear combined radial load and slight bidirectional axial load, stable low-friction rotation performance. Pre-filled anti-wear lithium grease inside the bearing, suitable for dusty outdoor farm, mining and workshop conveying environments. All rolling components are made of fully quenched GCr15 bearing steel with ultra-precision superfinished raceway, excellent anti-impact and anti-wear performance. Widely used in grain conveyors, feed mixers, lawn machinery, light mining belt conveyors and various vibration-prone transmission equipment.
