A DCB Roller is a specialized type of roller designed to follow the curvature of a cam or track and to translate or communicate machine motion or load. DCB Roller assemblies are manufactured with two rows of cylindrical roller bearings to withstand moderate to heavy loads and improves upon the traditional cam follower, to better accommodate combination loads. PCI’s ∞ Infinity Roller ™ Technology offers unparalleled performance in the most demanding environments by targeting and addressing the vulnerable areas of the assembly. PCI DCB Rollers feature guided custom profiled rolling elements, enhanced grease capacity and rugged rubber seals equaling an optimized design for maximum life. PCI’s ∞Infinity Roller™ Technology boasts extended life when compared to any other products on the market. Choose from stud type or yoke type in plain and crowned body profiles with black oxide coating on all surfaces.
Feature & Benefit Sell Sheets
Stud Type Concentric
Stud Type DCB Rollers provide efficient cantilever mounting. The hex socket in the integral stud provides additional installation torque for use with self-locking nuts and blind hole mounting.
Stud Type Eccentric
Eccentric Stud DCB Rollers provide a means of precision positioning between the roller and the track or rail surface. This feature allows for adjustment to provide uniform loading amongst mounted rollers.
Eccentric rollers are represented by “E” in the part number.
Yoke Type DCB Rollers
Yoke Type DCB Rollers provide higher load carrying capability by utilizing a double shear mounting arrangement thereby eliminating stud capacity limitations. Can be used with PCI Heavy Duty Yoke Shafts for efficient design & installation practices.
Yoke rollers are represented by “Y” in the part number.

Roller Body Profiles
Plain DCB Rollers
Plain/Cylindrical DCB Rollers effectively carry radial loads. For heavy side loads, Plain DCB Rollers can be positioned vertically to act as side guides.
Crowned DCB Rollers
Crowned DCB Rollers have a spherical body profile and are used to reduce the effects of misalignment by better distributing load over the body and internal bearing elements. Crowned rollers are also used in rotary applications to minimize scrubbing or skidding.
Heavy Duty Yoke Shafts
PCI precision carbon steel yoke shafts are carefully designed and machined to tight tolerances to ensure optimum fit and dependable performance with Yoke Type Load Bearing Roller Assemblies.
