C35 Prismatic Roller C35-2RS ZZ for Compact T- and U-rail Rail Size 35mm Concentric Stud Double Shields

The C35 prismatic roller is a dedicated guide component engineered for 35mm compact T- and U-type rails, featuring a prismatic profile that fits tightly with the rail’s inner contour—ensuring stable load distribution in limited installation spaces. Its concentric stud structure (integrated high-strength bolt shaft) enables direct, tool-free alignment and installation, while the double shield options (2RS rubber seals / ZZ metal seals) provide targeted protection: 2RS blocks dust and light moisture for general industrial scenarios, and ZZ resists high temperatures for continuous-operation equipment. The roller body is crafted from premium GCr15 bearing steel (hardness 58-62 HRC) with precision-ground raceways, and the concentric stud uses 40Cr high-strength steel (quenched to 45-50 HRC), delivering reliable load-bearing for light-to-medium duty guide tasks.

Compact automated assembly line guide systems, light-duty warehouse shelf sliding mechanisms, office automation equipment (e.g., printer paper feed rails), small logistics micro-conveying systems, medical device precision sliding components, electronic product testing equipment guide structures

• Directly interchangeable with INA C35 series prismatic rollers (matching 35mm T/U-rail and concentric stud specifications)
• Compatible with SKF compact guide prismatic roller equivalents for 35mm rails
• Domestic alternative: ZWZ C35-type prismatic rollers with concentric stud and double shields

1. Q: What’s the advantage of the prismatic profile for 35mm T/U-rails?

   A: The prismatic shape matches the inner contour of 35mm T/U-rails, eliminating lateral play and ensuring more stable load transmission than circular rollers in compact spaces.

2. Q: When should I choose 2RS vs. ZZ seals for C35 rollers?

   A: Choose 2RS for general dust/moisture protection in standard environments; ZZ is better for high-temperature (≤120℃) continuous-operation scenarios.

3. Q: What’s the recommended tightening torque for the concentric stud?

   A: For the M12 stud, the recommended torque is 20-25 N·m—this balances installation stability and avoids over-tightening damage.
