CNB-128-SB 4.00" Needle Cam Follower

Standard Needle Bearing Cam Followers and Cam Yoke Rollers

Carter Standard Type bearings are easily mounted and ideally suited for many cam or track roller applications with moderate loading and shock. The bearings are sealed to help prevent contamination and retain lubrication. This Standard Type is recommended for applications where the stud hole can be accurately machined to within +.0000" and -.0005". For other applications where these tolerances cannot be held to these limits, the Eccentric Type is recommended.

The outer race on Carter Cam Followers is high carbon chrome bearing steel thrrough-hardened and ground. The studs and inner races are low carbon alloy steel carburized and induction hardened. A zone hardened raceway leaves the shank end ductile. The needle rollers are high carbon chrome bearing steel through-hardened and ground.

Carter Needle Bearing Cam Followers are available as sealed bearings with a slotted head, a hexagonal socket, or a crowned O.D. Carter also offers sealed or unsealed needle bearing Cam Yoke Rollers for supporting heavier loads.

TYPES

Sealed with Slotted Head

Type CNB-S is the Standard Type having a slotted head which normally supplies sufficient turning ability for installing this type of bearing.

Sealed with Hexagonal Socket

Type CNB-SB provides the ease of installing with a hex wrench which may be desired particularly on the larger sizes.

Sealed with Crowned O.D.

Type CCNB-S is recommended wherever variations in dimensions of alignment of the tracks or cam might cause excessive angular loading. It reduces thrust on the rollers and wear, and aids reliability.

Eccentric Stud

Type CNBE is designed for applications where holding close tolerances of the mounting holes may prove difficult. Available in slotted or hexed versions. The eccentric bushing is made of cold drawn steel so you can drill or dowel through the housing and into the stud for permanent locking. In most cases, the clamping action of the mounting nut is sufficient.
