BECO BJ20U-2RS PTFE Lined Spherical Plain Bearing Sealed
Available
BECO maintenance-free radial spherical plain bushings — spherical plain bearings — carry heavy radial load while letting the shaft sit out of square, which is the job a rolling bearing cannot do.
The outer ring carries a PTFE sliding layer running against a hard chromium plated inner ring, so the joint runs dry. No grease point, no relubrication schedule. Sealed on both sides to keep dirt and water off the sliding surfaces, which is what lifts service life in exposed positions.
Suits fixed-direction loads and any position where oil or grease is unwanted, or simply cannot be reached.
