Product Description

What this part is

MRC 7217DU single-row angular contact ball bearing, 85 x 150 x 28 mm. Bore Diameter: 85 mm. Outside Diameter: 150 mm. Overall Width: 28 mm. Total Width: 28 mm. Contact Angle: 29°. Number Of Rows: 1. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Bearing Material: Chrome steel. Mounting Arrangement: Universally matchable. Design Units: Metric. Series: 7200. Base Number: 7217. Part Number: 7217DU. Unit Quantity: 1 Pc.

Decoding the designation

7217 — MRC 7200 light series angular contact ball bearing, 85 mm bore.

No type letter — 29° contact angle, the MRC standard angular contact execution.

DU — single universally ground bearing, one half of a matched pair.

What these specs mean in practice

Contact Angle: 29°. A 29° angle takes substantially more axial load than a 15° bearing while turning faster than a 40° one. It is the angle MRC uses right across its plain 7000 range.

Mounting Arrangement: Universally matchable. The ground ring faces let two or more pieces sit back-to-back, face-to-face or in tandem straight from the box, with the preload set by the grind rather than by shims.

Mounting data

Shaft seat 85 mm. Housing bore 150 mm. Ring width 28 mm. The 85 x 150 x 28 mm envelope is the ISO 7217 light-series size.

Quantity and configuration

Unit Quantity: 1 Pc. One universally ground single bearing, the half-pair execution MRC codes DU. Two pieces stack to a 56 mm mounted width when paired.

Interchange guidance

Cross-Reference 1: MRC 7217DU. The 85 x 150 x 28 mm envelope is the ISO 7217 size, so SKF 7217 BECBM, FAG 7217-B-XL-TVP and NSK 7217B share the boundary dimensions. Those are 40° executions and are a related size rather than an interchange: the load path angle differs and a swap changes the thrust-to-speed balance of the assembly. A direct interchange has to match the 29° angle as well as the envelope. Searchable variants of the manufacturer number: 7217DU, 7217-DU, 7217 DU, 7217D.
