You can always check the current price and availability of rollers after logging in to our online store.
Worth knowing:
- Shafts, made of Ck55/Cf53 materials, surface hardened to 59±6 HRC ensure maximum linear bearing life.
- Precise roller grinding allows for obtaining a surface roughness of 0.2 m.
- Shafts made of Ck55/Cf53/ .
- The soft core ensures high strength parameters and allows for subsequent processing.
- It is possible to perform turning and milling processing in our company's machining center.
- Implementation of machining based on the manufacturing drawings provided by the client or provided patterns.
- Metric sizes with diameters from 3 mm to up to 100 mm and inch sizes with a diameter from 1/4" to 3' available from stock.
- Shafts cut to size within a tolerance of ±0.2 mm, higher accuracy on request.
- For environments exposed to corrosion, we offer rollers made of martensitic stainless steel: X46Cr13(1.4034)< /span> — surface hardened to 52±2 HRC and X90CrMoV18 (1.4112) — surface hardened to >55 HRC, both types of steel available from stock.
- Fundamental differences between both steel grades X46Cr13 (1.4034) and X90CrMoV18 (1.4112) :

- higher steel corrosion resistance X90CrMoV18, resistance to fresh water and steam and resistance to operating temperatures < 400℃.
- steel X90CrMoV18 undergoes heat treatment and obtains hardness and high abrasion resistance unusual for corrosion-resistant steels, and is also highly polished
- steel X46Cr13 is well machinable, hardenable and polish
- X46Cr13 steel has sufficient corrosion resistance to environments containing certain organic acids, substances without chlorides, weak alkalis.
- Generally, X46Cr13 steel and X90CrMoV18 steel are stainless steels, they are not suitable for use in acidic environments; acid-resistant steels are required there
