Roller Follower Cylindrical Yoke Roller Assembly (YCRS)

• Yoke-type track roller.
• Non-separable unit with outer ring, a full complement of needle rollers, inner ring, self-lubricating resin internal thrust washers, and two retaining washers securely fastened to the inner ring.
• Seals in counterbores of outer ring seal against the retaining washers; retain lubricant and exclude foreign matter (YCRS Series).
• Crowned outer ring to support the uneven bearing load.
• Tolerance limits for outer diameters of stud and outer ring refer to "single mean diameter".
• The machine element with the holes in which the mounting bolt is supported must be sufficiently rigid to resist local crushing under the applied load and to resist bending which can cause uneven loading of the rollers.
• When the applied loads are high, the tight transition fit should be used in conjunction with a high-strength shaft or bolt.
• When loads are moderate, the loose transition fit may be used with a high-strength shaft or bolt. For light loads, the loose with a high strength shaft or bolt. For light loads, the loose

About Track Roller

• Track rollers (also known as cam followers) are characterized by their thick-walled outer rings that run directly on a track.
• The thick outer rings permit high load-carrying capability while minimizing both distortion and bending stresses.
• Sealed designs with internal thrust washers help extend service life under conditions of infrequent lubrication.
