Product Description

What this part is:

MRC 407-R single-row angular contact ball bearing, MRC 400-R Heavy Series. Bore Diameter: 35 mm (1.3780 in). Outside Diameter: 100 mm (3.9370 in). Width: 25 mm (0.9843 in). Contact Angle: 15°. Precision: ABEC 3. Number Of Rows: 1. Rolling Elements: Steel balls. Closure Type: Open. Unit Quantity: 1 Pc. Thrust capacity acts in one direction.

Decoding the designation:

407 — bore code, 35 mm, in MRC’s 400 Heavy Series.

R — R-type construction, a single-row 15° angular contact bearing with a counterbored outer ring.

Carton markings — 407R, 407-R and 407 R.

Specifications:

Bore Diameter: 35 mm. Outside Diameter: 100 mm. Width: 25 mm. Contact Angle: 15°. Precision Rating: ABEC 3, with tighter bore, outside-diameter and runout tolerances than ABEC 1. Series: MRC 400-R Heavy Series. Material: Chrome steel. Harmonization Code: 8482.10.50.28.

Dimensions and mounting:

The Heavy Series section has a 100 mm outside diameter at a 35 mm bore, against 62 mm for an ISO 6207 deep groove bearing on the same shaft. That section carries very heavy radial load, heavy one-direction thrust, or a combination. The 15° contact angle keeps speed capability high relative to 25° or 40° bearings. Maximum shaft fillet radius cleared by the bearing corner, ra: 1.5 mm (0.06 in). Maximum housing fillet radius, rb: 1.0 mm (0.040 in). The counterbored side is the low-shoulder face and does not carry thrust.

Compatibility and replacement:

Cross-reference: 7407-C. The 407-R shares its 35 x 100 x 25 mm envelope and 15° contact angle with the ISO 7407 C heavy angular contact section, carried on the carton as 7407-C. Two 407-R bearings mounted back-to-back form the 407-RD duplex arrangement, 35 x 100 x 50 mm, which takes thrust in both directions. MRC has obsoleted the 400-R and 400-RD Heavy Series.
