INAGLE40KRRBRadial Insert Ball Bearing – 40 mm Bore, 80 mm OD, Spherical Outer Ring, Non-Locating, Drive Slot, Sealed Both Sides

Product Description

What this part is

INA GLE40-KRR-B radial insert ball bearing with a spherical outer ring. The spherical outer surface lets the bearing align itself inside a matching housing, and the inner ring carries a drive slot instead of a locking collar. Bore Diameter: 40 mm. Outside Diameter: 80 mm. Total Width: 42.9 mm. Outer ring width: 21 mm. Dynamic Load Rating: 34,500 N. Static Load Rating: 19,800 N. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: R seals both sides. Expansion Type: Non-locating. Item Weight: 0.56 kg (1.23 lb). Series: GLE. Base Number: GLE40. GTIN: 4012802799576.

Decoding the designation

G — radial insert ball bearing with a spherical outer ring, for mounting in a housing unit or a machine bore of matching form.

LE — non-locating execution with a drive slot machined into the inner ring bore. The slot transmits drive without the axial shaft clamp that an eccentric collar or grub screw applies, so the shaft is free to expand through the bearing.

40 — bore diameter in millimetres.

KRR — R seals on both sides, retaining the grease charge.

B — the current Schaeffler design generation for this insert family.

XL — Schaeffler’s current-generation designation; GLE40-XL-KRR-B supersedes GLE40-KRR-B.

What these specs mean in practice

Dynamic Load Rating: 34,500 N against a Static Load Rating of 19,800 N. That ordering is normal on radial insert ball bearings and reflects the wide inner ring and relatively light ball complement: the design is dimensioned for running load rather than shock. Fatigue load limit: 910 N.

The non-locating design suits the free end of a shaft on a conveyor, fan or agricultural drive, where thermal growth has to go somewhere.

Mounting data

Spherical outer ring seating diameter: 80 mm. Rib diameter, inner ring: 52.3 mm. Distance from the raceway: 15.9 mm. Distance to lubrication hole: 6.4 mm. Outside diameter over the seal: 68.3 mm. Sealing total width: 23.5 mm.

Retaining slot: 9 mm high, 7 mm wide, machined to H11.

Quantity and configuration

Unit Quantity: 1 Pc. Bearing insert only, with both R seals fitted.

Interchange guidance

The GLE non-locating drive-slot insert is a Schaeffler design, so the wide cross-maker interchange that applies to setscrew and eccentric-collar inserts does not carry across to it. The GE40-XL-KRR-B is the same 40 x 80 mm envelope in the eccentric locking collar execution. Designation variants: GLE 40 KRRB, GLE40KRRB, GLE40-KRR-B, GLE40-XL-KRR-B.
