AKE 21315BHL double-row spherical roller bearing. Bore: 75 mm. Outside diameter: 160 mm. Width: 37 mm. Series: 213, ISO dimension series 13. Two rows of barrel-shaped rollers run on a single spherical raceway ground into the outer ring, so the inner ring and roller assembly swivel inside that race and the bearing self-aligns. It carries very heavy radial load plus axial load in both directions, and is the standard choice for conveyor pulleys, fans, crushers, screens, mixers and mill drives.
Ring marking: 21315 BHL. Searchable forms: 21315BHL, 21315-BHL, 21315 BHL, 21315HL, 21315-HL, 21315 M, 21315M, 21315. Base Number: 21315. Bore code 15 gives a 75 mm bore. Carton hand-marking: 21315 M. Both markings travelled with this part and both are carried in the cross-references.
Bore Type: straight cylindrical. The bearing mounts directly on the shaft with an interference fit. Lubrication provision: housing-fed, with a plain outer ring. Closure: open, non-sealed.
Cage Material: machined brass. Cage Type: machined. A machined brass cage runs cooler under high load than pressed steel, tolerates higher temperature and marginal lubrication, and absorbs shock and vibration well — the reason it is specified for screens, crushers and vibrating duty.
The 213 series is the low, narrow cross-section among the spherical roller series. A 22315 or 22215 of the same 75 mm bore has a larger outside diameter, greater width and higher load ratings, and takes a different housing bore. A 21315 position is replaced by the 21315 envelope: 75 × 160 × 37 mm.
Bore d: 75 mm. Outside diameter D: 160 mm. Width B: 37 mm. Number of rows: 2. Rolling elements: spherical (barrel) rollers. Internal Clearance: CN. Closure: open. Design Units: metric. Harmonization Code: 8482.30.00.
Bore form: straight cylindrical, for an interference fit on the shaft. Self-alignment: the bearing is self-aligning, so modest housing misalignment is accommodated by design.
Unit Quantity: 1 Pc, sold individually. Scope of supply is the bearing. New old stock in factory poly bags, in aged AKE cartons carrying hand-written stores markings, with preservative oil present.
21315 is an ISO base number, so 75 × 160 × 37 mm spherical roller bearings are available from every major maker. Straight-bore equivalents: SKF 21315 E, FAG / Schaeffler 21315-E1-XL, NSK 21315EAE4, NTN 21315, Timken 21315EJW33C3, Koyo 21315R. Suffixes: /C3 or -C3 for C3 clearance, /W33 for the outer-ring lubrication groove. Tapered-bore versions of the same envelope are SKF 21315 EK and FAG 21315-E1-K, which mount on an adapter sleeve. Crossing matches bore type, clearance class and W33 provision beyond the base number. Most modern tier-one 213 series parts ship with pressed steel cages, so a machined brass cage is specified deliberately.
