RHP7303ETDULP4Super Precision Angular Contact Ball Bearing Pair 17x47x14 mm, 25° Contact Angle, Light Preload, ABEC 7

Product Description

What this part is:

Matched pair of super-precision angular contact ball bearings, 17 mm bore x 47 mm outside diameter x 14 mm width, ISO 7303 size. Single row each, machined phenolic cage, universally ground for light preload. Unit Quantity: 2 Pcs.

Decoding the designation:

7303 — ISO 73 series size, 17 x 47 x 14 mm.

E — 25° contact angle.

T — machined phenolic cage.

DUL — duplex universal grinding, light preload.

P4 — precision class equivalent to ABEC 7.

B7303X3TADULEP7 — RHP B-series form of the same part; X3 gives the 25° angle and EP7 the P4 class.

3MM303WI CR DUL — Fafnir-scheme form; 3MM gives 25° and CR a phenolic cage.

Specifications:

Bore Diameter: 17 mm. Outside Diameter: 47 mm. Width: 14 mm. Contact Angle: 25°. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Cage Type: Machined, outer-ring land-riding. Preload: Light. Mounting Arrangement: Universal (DB, DF or DT). Series: 7300. Number Of Rows: 1 per bearing. Total Width: 28 mm (pair, clamped solid). Unit Quantity: 2 Pcs.

Dimensions and mounting:

Each bearing carries radial load with thrust in one direction. Mounted back-to-back or face-to-face the pair locates the shaft in both axial directions; mounted in tandem both act in the same direction. Universal grinding gives the specified light preload in any of these arrangements.

Compatibility and replacement:

Cross-references: NSK 7303A5TDULP4 (A5 = 25°); Timken 3MM303WI CR DUL. Same-size 15° (C), medium or heavy preload, and P5 or P6 versions are related sizes with different specifications.

Frequently asked questions:

What contact angle does the 7303ETDULP4 have?
