BECO BJ25W PTFE Lined Angular Contact Spherical Plain Bearing, Open, 25 x 47 x 15 mm

BECO maintenance-free angular contact spherical plain bearings to DIN ISO 12240-2 carry combined radial and one-directional axial load while still letting the shaft sit out of square. The angled contact face takes thrust in one direction as well as the radial load. The outer ring carries a PTFE sliding layer running against a hard chromium plated inner ring, so the joint runs dry, with no grease point and no relubrication schedule. That suits fixed-direction loads and any position where oil or grease is unwanted or cannot be reached.

It is supplied open: with no grease to retain, the PTFE liner needs no seals. This range has 17 sizes with bores from 25 to 100 mm.

Where this product is used

• Steering and tilt linkages
• Mast and boom pivots

Key specifications

Available sizes

Selecting the right option

Select by bore d first, then check the outside diameter D, ring width and sphere diameter dK in the table against the housing and the mating part.

Dynamic and static load ratings are not listed on this page. Contact AIMS Industrial to confirm ratings against your application before ordering.

PTFE lined joints suit steady, fixed-direction loads. For shock or alternating loads, the steel on steel type is the one built for it.

Fitting and use

Press only on the ring being fitted, and never through the sliding surfaces of the joint.

PTFE lined bearings are maintenance-free and need no relubrication.

Contact AIMS Industrial for help choosing the fit and the service interval for your application.
