C4168K30MB/C3 CARB Toroidal Roller Bearing
Selection Guide
Work through the checks in order: do the mounting dimensions (bore, outside diameter, width or height) match your shaft and housing; do the dynamic load rating Cr and static load rating Cor meet your load and life requirements; is the limiting speed above your actual operating speed with margin; and do the clearance and accuracy classes suit the duty. If you already have a bearing in service, send us the complete designation with suffixes and we will verify interchangeability and quote. For a new design, send load, speed and environmental conditions and we will help select.

Yes—CAD/DXF/PDF high-precision drawings and 3.1 material certificates (GCr15 bearing steel) for C4168K30MB/C3 are available on request from RAYSDE.
C4168K30MB-C3 How do I confirm this model can replace the bearing I have now?
Send us the complete designation and all suffixes of your existing bearing, or measure and photograph the three key dimensions — bore, outside diameter and width (or height). Most standard bearings interchange by ISO dimension series, but suffix differences (sealing, clearance, cage, accuracy) affect performance, so we check each item before quoting and only release supply once dimensions and key characteristics are confirmed. This avoids clearance or speed mismatch after fitting.
C4168K30MB-C3 What information do you need to place an order, and what is the minimum quantity?
To order we need: the complete designation with suffixes, quantity required, accuracy and clearance requirements, and your target delivery date. Minimum order quantities for standard items are tiered by bore: 500 pieces up to 50 mm, 100 pieces for 51–100 mm, 20 pieces for 101–300 mm and 4 pieces above 300 mm; non-standard items are negotiated against drawings. We operate as a supplier and OEM sourcing service, with partner factories certified to ISO 9001:2015, and we can provide 3.1 material certificates.
