BECO BJ20A PTFE Lined Thrust Spherical Plain Bearing Open
Available
BECO maintenance-free thrust (axial) spherical plain bushings — spherical plain bearings to DIN ISO 12240-3 — carry pure axial load centred on the bearing axis, while still letting the shaft sit out of square.
The housing washer carries a PTFE sliding layer running against a hard chromium plated shaft washer, so the joint runs dry. No grease point, no relubrication schedule. That suits fixed-direction loads and any position where oil or grease is unwanted, or simply cannot be reached.
Supplied open — with no grease to retain, the PTFE liner needs no seals.
