Dimensions, materials, performance and availability are confirmed for each inquiry. Photos show product examples; the finished specification is agreed for your application.
01 / What to discuss
Choose an elastomer family and target hardness.
Match the bearing core to the installation dimensions.
Confirm the final profile, coating thickness and working conditions.
02 / Useful details for your inquiry
Bearing core reference and finished dimensions
Elastomer grade and target hardness with scale
Contact media, load, speed and environment
MATERIAL & BEARING CORE
Choose the surface. Then the bearing inside.
Keep the outer material and bearing core separate when discussing a production configuration.
Soft elastomers
Rubber coated bearings
This product family
PU · polyurethane
Confirm the elastomer grade, target hardness, contact surface and coating thickness.
NR · natural rubber
Confirm the compound, target hardness, contact needs and operating environment.
EPDM rubber
Review the compound, temperature, contact media and environment.
VMQ · silicone rubber
Confirm the specific grade, temperature and contact requirements.
CR · chloroprene rubber
Review the compound, hardness, contact media and conditions.
FKM · fluoroelastomer
Confirm the grade, temperature, contact media and production process.
Confirm the grade, outer profile, dimensions and mounting fit.
PA · nylon
Confirm the nylon grade, humidity, temperature and dimensional needs.
PA+GF · glass-filled nylon
Confirm the nylon base, glass content, structure and surface requirements.
PE · HDPE / UHMWPE
Specify the grade and review forming, machining and assembly.
PP · polypropylene
Confirm the grade, profile, temperature and mounting requirements.
PTFE · polytetrafluoroethylene
Confirm the grade, dimensions, machining and assembly.
These material families are offered for SUTEWEI product discussions. The elastomer and rigid-plastic groups describe the intended surface; actual hardness depends on the grade, compound and measurement. Confirm the grade, reinforcement, colour and process. Each material and bearing combination needs its own review.
Bearing families & application direction
Miniature series
Compact mechanisms and limited installation space
607 / 6086000 series
Light conveying requirements
6000 / 60016200 series
Medium-duty requirements · core range
6200 / 62016300 series
Higher-duty and castor requirements
6300 / 6301
Series and application directions are an initial guide. Load, speed and service life must be checked for the actual model, size and conditions.
