B 1.0000 / D 2.1250WPB16TG is a wide-series PTFE-lined spherical bearing with staking groove, bore (B) = 1.0000″, OD (D) = 2.1250″. Body width (W) = 1.375″, inner race width (T) = 1.005″. Ball diameter = 1.875″. Flat OD (O) = 1.269″. Approximate weight: 0.970 lb.
Rated at 104,000 lb static radial load with ±12.0° misalignment angle. The staking groove on the OD allows the bearing to be permanently retained in a housing bore by staking the housing material into the groove — eliminating the need for snap rings or press-fit retention in many assemblies. The 52100 bearing steel ball is precision ground, heat treated, and hard chrome plated. The alloy steel race is heat treated, oil coated, and PTFE lined for self-lubricating operation.
Stainless race + stainless ball: add ‘-SS’ suffix (e.g., WPB16TG-SS). Stainless race + steel ball: add ‘-S’ suffix (e.g., WPB16TG-S). Non-groove variant: WPB16T (WPB-T series). Standard-width Teflon-lined equivalent: COM-T series.

The WPB16TG is a wide-series, PTFE-lined spherical bearing with a staking groove on the OD, with a 1.0000" bore and 2.1250" OD — the staking groove lets it be permanently retained in a housing bore by staking the housing material into the groove, eliminating the need for snap rings or press-fit retention in many assemblies.
Bore (B) is 1.0000", OD (D) is 2.1250", body width (W) is 1.375", inner race width (T) is 1.005", ball diameter is 1.875", and flat OD (O) is 1.269" — approximate weight is 0.970 lb.
The WPB16TG is rated at 104,000 lb static radial load with up to ±12.0° of angular misalignment.
The alloy steel race is heat treated, oil coated, and PTFE lined, so the ball articulates against a low-friction PTFE surface instead of requiring grease — this is what makes the WPB16TG maintenance-free in service.
The ball is 52100 bearing steel, precision ground, heat treated, and hard chrome plated; stainless steel is optional. The race is alloy steel, heat treated, PTFE lined, and oil coated; stainless steel is optional and zinc plating is optional. For a stainless race with a stainless ball, add the '-SS' suffix (e.g., WPB16TG-SS). For a stainless race with a standard steel ball, add the '-S' suffix (e.g., WPB16TG-S).
The WPB16TG is the staking-groove version of this bore/OD size. The non-groove variant is WPB16T (WPB-T series), and the standard-width Teflon-lined equivalent is the COM-T series — choose based on whether you need the retention groove and on your width requirement.
