MRC214RDSAngular Contact Ball Bearing – 70 mm ID, 125 mm OD, 24 mm Width, Open, 15 ° Contact Angle, ABEC 7.

Product Description

What this part is

MRC 214RDS is a single-row angular contact ball bearing in the 200 light series. Bore is 70 mm, outside diameter is 125 mm, and section width is 24 mm. The bearing runs open with no seal or shield, and the rings are steel. Precision Class: ABEC 7 / P4.

Decoding the designation

Series: 200, light. Bore code 14 gives a 70 mm bore. Type letter R sets the contact angle at 15° with a counterbored outer ring. Execution code DS marks a half pair ground for preload.

What these specs mean in practice

A 15° contact angle carries less thrust and more speed than a 40° angle, which suits spindle and drive positions where shaft location governs. The 200 light section keeps outside diameter modest for a 70 mm bore. ABEC 7 grade buys tighter bore, outside diameter and running-accuracy tolerance, lower running vibration and closer, more repeatable shaft location than a standard grade. DS grinding sets a defined preload when the rings are drawn up, which removes axial play and raises system stiffness.

Quantity and configuration

Two pieces ship, matching the 2 pcs count carried in the title. Mounted together the two DS halves form one preloaded duplex set. The carton and ring markings BKE#7 and 2MM214 WI CR DUL are carried in MPN Variants for search.

Fitting notes

Internal clearance reads N/A because a DS-ground bearing takes its running clearance from the preload set at assembly rather than from a radial clearance class. Faces are ground so the halves seat solid against each other and against the shoulders. The counterbored outer ring carries the full ball complement on one shoulder, which is what gives the angular contact bearing its one-direction thrust capacity.
