Yoke Type Track Roller Bearings<\/h1><\/div>\n\n\n\n

Yoke type track rollers are critical components in heavy machinery, particularly in construction and material handling equipment, where they support and guide tracks under demanding conditions.<\/p><\/div>\n\n\n\n

These rollers feature thick-walled outer rings, often with a crowned or cylindrical outer surface, to distribute loads evenly. They may incorporate needle rollers, cylindrical rollers, or ball bearings, depending on the series and application.<\/p><\/div>\n\n\n\n

ZMS Bearings Co.,Ltd supplies very full series of yoke type track roller bearings in China. With high quality and affordable price and stocking, we can supply fast plan for customer choose. Although the series are a lot, we are patience and professional of each series.<\/p><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n

Thick-Walled Outer Rings for Maximum Shock Loads<\/strong><\/h2>\n\n\n\n

Unlike standard bearings mounted inside a housing, track rollers are designed to run directly on mating tracks or cam drives. To withstand massive rolling loads and sudden shock impacts without deforming, ZMS yoke type track roller bearings are engineered with exceptionally thick-walled outer rings<\/strong>. This rugged construction ensures reliable linear guidance in conveyor systems, packaging machinery, and automated transfer lines.<\/p>\n\n\n\n

Yoke Type vs. Stud Type: What\u2019s the Difference?<\/strong><\/h2>\n\n\n\n

When designing a linear guidance system, engineers must choose between yoke type and stud type rollers:<\/p>\n\n\n\n

    \n
  • Yoke Type Track Rollers:<\/strong> Designed to be straddle-mounted on a shaft or pin (supported on both sides by a clevis or bracket). This double-support mounting handles heavier loads and prevents the bending stresses associated with cantilevered designs.<\/li>\n\n\n\n
  • Stud Type (Cam Followers):<\/strong> Have an integrated threaded solid stud for cantilever mounting (supported on one side only).<\/li>\n<\/ul>\n\n\n\n

    Crowned vs. Cylindrical Outer Ring Profiles<\/strong><\/h2>\n\n\n\n

    Misalignment between the roller and the track is common in industrial environments, leading to damaging edge stresses and premature failure.
    ZMS track rollers are available with a crowned (convex) outer ring profile<\/strong> (often indicated by an “R” suffix). This crowning compensates for minor misalignments, distributes the load evenly across the rolling elements, and significantly extends the service life of both the bearing and the track. Standard cylindrical (flat) profiles are also available for applications with highly precise track alignments.<\/p>\n\n\n\n

    Standard Series for Every Application (NATR, NATV, NUTR, PWTR)<\/strong><\/h2>\n\n\n\n

    We manufacture a comprehensive range of yoke type track rollers to match your specific speed and load requirements:<\/p>\n\n\n\n

      \n
    • NATR Series:<\/strong> Cage-guided needle roller design, ideal for high-speed linear motion.<\/li>\n\n\n\n
    • NATV Series:<\/strong> Full complement needle roller design for increased radial load capacity at lower speeds.<\/li>\n\n\n\n
    • NUTR \/ PWTR Series:<\/strong> Full complement cylindrical roller design with heavy-duty lip seals, offering the absolute highest load ratings and excellent protection against contamination.<\/li>\n<\/ul>\n\n\n\n
