MRC 7310DS single-row angular contact ball bearing, 50 x 110 x 27 mm. Bore Diameter: 50 mm. Outside Diameter: 110 mm. Overall Width: 27 mm. Total Width: 27 mm. Contact Angle: 29°. Precision Class: ABEC 5 / P5. 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: 7300. Base Number: 7310. Part Number: 7310DS. Unit Quantity: 1 Pc.
7310 — MRC 7300 medium series angular contact ball bearing, 50 mm bore.
No type letter — 29° contact angle, the MRC standard angular contact execution.
DS — single universally ground bearing, one half of a matched pair.
Contact Angle: 29°. A 29° angle takes substantially more axial load than a 15° bearing while turning faster than a 40° one.
Precision Class: ABEC 5 / P5. Bore, outside diameter and running accuracy are held to roughly half the tolerance band of a standard ABEC 1 bearing, which shows up as lower runout and lower vibration at speed.
Series: 7300. The medium series carries a heavier ball set than the 7200 light series on the same bore.
Shaft seat 50 mm. Housing bore 110 mm. Ring width 27 mm. Mounting Arrangement: Universally matchable. Universally ground 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.
Unit Quantity: 1 Pc. One universally ground single bearing, the half-pair execution MRC codes DS.
Cross-Reference 1: MRC 7310DS. The 50 x 110 x 27 mm envelope is the ISO 7310 size, so SKF 7310 BECBM, FAG 7310-B-XL-TVP and NSK 7310B 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: 7310DS, 7310-DS, 7310 D S.
