Product Description

Rexnord Link-Belt P3U227H standard-duty pillow block ball bearing unit, Series 200. Bore / Shaft Size: 1-11/16 in, round bore. Housing Style: Two-bolt base pillow block. Housing Material: Cast iron, powder coated. Locking Method: Set screw. Expansion Type: Non-expansion, fixed. Seal Type: Clearance seals, floating labyrinth. Rolling Elements: Balls, deep groove, wide inner ring. Insert Size Code: 209. Relubrication: Relubricatable. Rexnord item number: 10419978. GTIN: 662327121105. Country of Origin: Mexico.

Housing style and bolt pattern

Bolt Center To Center Length: 5-11/16 in (5.6875 in). Base To Bore Centerline: 2-1/8 in (2.125 in). Base Width: 2 in. Overall Length: 7-1/4 in. Overall Width: 2-1/32 in. Overall Height: 4-5/16 in. Two fastener holes in the base.

What these specs mean in practice

Dynamic Load Rating: 7,370 lb (32.8 kN). Static Load Rating: 4,590 lb (20.4 kN). Maximum Speed: 5,330 rpm. Maximum Operating Temperature: 225 °F (107 °C). Minimum Operating Temperature: -30 °C. Lubricant: Grease. The insert is a precision alignable deep groove ball bearing, so the unit takes up shaft misalignment at assembly and then runs in a fixed position. A wide inner ring gives the set screws more length to grip and steadies the shaft. The one-piece cast iron housing is stiffer than a two-piece split block of the same size and carries the load straight into the mounting surface.

Quantity and configuration

Unit Quantity: 1 Pc. Complete mounted unit: housing, bearing insert, seals and set screws.

Installation and setup notes

Expansion Type: Non-expansion. On a two-bearing shaft this unit sets the axial position, and a second expansion unit takes the thermal growth. Set screws lock the inner ring to a plain round shaft, so no adapter sleeve or tapered seat is involved. Series 200 standard-duty units carry radial load or combined radial and thrust load. Harmonization Code: 8483.20.40.
