BECO BJ17XA Thrust Spherical Plain Bearing, Open, 17 x 47 x 16 mm
Available
BECO thrust (axial) 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. A hardened steel shaft washer runs its spherical surface directly against a matching hardened steel housing washer, which gives this type very high static load capacity and tolerance of shock and alternating loads.
It is supplied open, for clean or regularly serviced positions. Steel on steel joints need periodic greasing, so plan it into the service schedule. This range has 15 sizes with bores from 10 to 100 mm.

Selecting the right option
Select by bore d first, then check the outside diameter D, height H, housing washer thickness 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.
Steel on steel suits shock and alternating loads and needs periodic greasing. Where the joint cannot be greased, choose a PTFE lined bearing.
Fitting and use
Press only on the washer being fitted, and never through the sliding surfaces of the joint.
Grease the bearing at the service interval for your duty, and keep the joint clean.
Contact AIMS Industrial for help choosing the fit and the service interval for your application.
