Overview
3208A is a double-row angular contact ball bearing with a 40 mm bore, 80 mm outer diameter and 30.2 mm width, part of the 32 Series family. Boundary dimensions follow GB/T 292 / ISO 15 for angular contact ball bearings and are cross-checked against the catalogue dimension tables.
The 32 Series (A design) is a double-row angular contact family that carries combined loads in both directions in one unit — useful where a pair of single-row bearings would be too wide. ZZ shields and 2RS seals are listed; grease fill and clearance to order. Closure options: ZZ, 2RS. Supplied in precision grades P0/P6/P5. Typical applications include pumps, gearboxes, agricultural machinery, machine tool spindles.
Double-row angular contact (A design). ZZ metal shields or 2RS contact seals available. Load ratings and limiting speeds on datasheet on request.
- Closure options: ZZ, 2RS — open, metal shield or rubber seal to suit dust and grease retention.
- Precision P0, P6, P5; clearance C0, C2, C3; noise grades ZV1, ZV2, ZV3.
- GCr15 chrome steel (100Cr6), 58–62 HRC; steel or nylon cage options.
- Stainless rings, ceramic balls and non-standard sizes can all be ordered to drawing; black chamfer, chamfer colour, custom grease and customer marking also available on request.
