INAPE40Radial Insert Ball Bearing – 40 mm Bore, 90 mm OD, Steel Aligning Ring, Eccentric Locking Collar, Sealed Both Sides

Product Description

What this part is

INA PE40 radial insert ball bearing with a cylindrical outer ring and a separate steel aligning ring. The aligning ring sits around the outer ring and gives the assembly a spherical outer form, so a cylindrical-bore insert can still align itself in a housing. The wide inner ring carries an eccentric locking collar for location on a plain shaft. Bore Diameter: 40 mm. Outside Diameter: 90 mm. Total Width: 45.2 mm. Outer ring width: 25 mm. Dynamic Load Rating: 32,500 N. Static Load Rating: 19,800 N. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: P seals both sides. Locking Method: Eccentric locking collar. Item Weight: 0.9 kg (1.98 lb). Series: PE. Base Number: PE40.

Decoding the designation

PE — radial insert ball bearing unit built from a cylindrical-outer-ring insert plus a steel aligning ring, located by an eccentric locking collar.

40 — bore diameter in millimetres.

XL — Schaeffler’s current-generation designation; PE40-XL supersedes PE40.

RAE40-XL-NPP-B — Schaeffler’s designation for the bearing insert inside this unit. NPP is the P seal on both sides; the N is the retaining groove in the outer ring.

What these specs mean in practice

Dynamic Load Rating: 32,500 N against a Static Load Rating of 19,800 N. That ordering is normal on radial insert ball bearings, which are dimensioned for running load rather than shock. Fatigue load limit: 1,030 N.

The steel aligning ring is what makes this different from an ordinary GE or UC insert: the bearing itself has a plain cylindrical outside diameter and the alignment happens between two separate steel surfaces, which suits a housing bored straight rather than spherically.

Mounting data

Housing bore: 90 mm over the aligning ring. Diameter of the retaining groove: 86.8 mm. Distance between ring grooves: 15.4 mm, with an upper tolerance of +0.2 mm. Width of the retaining slot: 2.7 mm. Locking collar nut: diameter lower tolerance −0.5 mm, width upper tolerance +0.3 mm.

Quantity and configuration

Unit Quantity: 1 Pc. Insert with eccentric locking collar, steel aligning ring and both P seals.

Interchange guidance

The PE insert-plus-aligning-ring construction is a Schaeffler design, so the wide cross-maker interchange that applies to spherical-outer UC and GE inserts does not carry across to it. The 40 mm bore, 90 mm outside diameter and 25 mm outer ring width are the dimensions that decide a substitution. Designation variants: PE 40, PE-40, PE40-XL, RAE40-NPP-B, RAE40-XL-NPP-B.
