| Setscrew locking mechanism is easy to install and
well-suited for reversing applications and normal loads. |
The self-locking collar eliminates the need for
locknuts, washers, shoulders, sleeves and adapters. |
These housed units are selected where setscrew
locking is preferred, but inner- ring stress and/or distortion are of major concern. |

Set Screw Locking Collar
1) Y Series
The GY-KRRB series of relubricatable and non-relubricatable bearings offer a full-width inner ring with specially designed setscrews to lock on shafting. The series also features a positive-contact, land-riding R-seal to protect against harmful contaminants and retain lubricant.
Full-width inner ring bearings are ideal where maximum shaft-surface contact is needed for added stability. For shaft protection, the GY-KRRB insert is equipped with shaft-guarding technology.
Design Attributes
- Full-width insert and a three-piece, fiber-imbedded R-seal.
- Setscrew locking mechanism is easy to install and well-suited for reversing applications and normal loads.
Applications
- Construction
- Conveyors
- Food and beverage
- General industrial equipment
- Packaging
2) S Series
The GYA-RRB series of relubricatable and non-relubricatable bearings offer an extended inner ring with specially designed setscrews to lock on shafting. The series also features a positive-contact, land-riding R-seal to protect against harmful contaminants and retain lubricant. Extended inner-ring bearings are used where space is at a premium and load overturn is not a problem.
Design Attributes
- Ideal for applications where space is at a minimum.
- Three-piece Buna-N contact seal with inner and outer shrouds to protect sealing and prevent seal-lip inversion.
- Setscrew locking mechanism is a good fit for reversing applications.
Applications
- Conveyors
- General industrial equipment
- Packaging
3) Shaft Guarding Technology
This Timken innovation prolongs shaft life while allowing easy installation and removal of a standard setscrew unit. Its technology minimizes shaft damage by protecting shafts from gouging, raised metal and fretting corrosion. These insert bearings are found where production uptime is critical and shaft replacement is expensive.
Design Attributes
- Design includes two conventional setscrews that do not dig into shafts in order to maintain grip.
- Setscrews transfer pressure to the shaft through a stainless-steel hardened band, eliminating direct shaft-setscrew contact.
- A groove runs beneath the setscrews in the inner-ring bore to keep this band stationary.
- The extended length of the inner ring also provides additional stability to improve shaft support and reduce bearing misalignment.
Applications
- Industrial equipment: fan and blower, food and beverage, conveyor, printing press, packaging and textiles
- Rubber and plastic
- Agriculture: combines and implements
