MRC7314-PJDEAngular Contact Ball Bearing – 70 mm ID, 150 mm OD, 35 mm Width, Straight Bore, Open, 40 Degree, Machined Bronze Cage, Universally Ground

Product Description

What this part is

MRC 7314-PJDE BRZ single-row angular contact ball bearing. Bearing type: Angular contact ball bearing. Bore: 70 mm. Outside Diameter: 150 mm. Overall Width: 35 mm. Contact Angle: 40°. Cage Material: Bronze. Cage Type: Machined. Bore Type: Straight. Closure Type: Open, both faces. Number Of Rows: 1. Rolling Elements: Ball. Series: MRC 7300 medium, ISO 73 dimension series. Unit Quantity: 1 Pc. GTIN: 097741036214.

Decoding the designation

73 — medium section angular contact series, matching the ISO 73 dimension series, with more radial and thrust capacity than a 72-series bearing on the same bore.

14 — bore code giving Bore: 70 mm.

P — Contact Angle: 40°, the high-thrust MRC execution.

DE — single universally ground with end play, so two or more of these clamp together to a repeatable axial end play rather than to a preload.

BRZ — Cage Material: Bronze, machined and one-piece.

What these specs mean in practice

Contact Angle: 40°. The steep angle runs most of the load path along the shaft axis, so this execution carries substantially more one-direction thrust than a 15° or 29° bearing in the same envelope, at a lower speed ceiling. That is what a pump thrust position, a compressor shaft or a vertical spindle is built around. Cage Material: Bronze, machined. A solid bronze cage tolerates higher temperature and shock loading than a pressed steel cage and runs well under marginal lubrication. Universally ground faces mean a stack of these bearings sets its own axial end play at assembly with no shims and no measuring.

Quantity and configuration

Unit Quantity: 1 Pc. One universally ground bearing, open on both faces, straight bore. It runs alone or stacks into a set with further bearings of the same designation.

Fitting notes

Straight bore on an interference-fit shaft seat, outer ring located in a bored housing. A single row locates axially in one direction, so the direction the bearing faces on assembly sets which way thrust is carried. Mounting force is applied through the ring being fitted rather than across the balls or the cage.

Interchange guidance

The 70 x 150 x 35 mm envelope at a 40° contact angle corresponds to the ISO 7314 B executions — SKF 7314 BE, FAG 7314-B and NSK 7314B. A 7314 AC at 25° or a 7314 C at 15° shares the same shaft and housing seats at a shallower angle and is a related size rather than an interchange.
