6903RS Thin Section Bearings

6903RS thin section bearings have become a cost-effective sealing solution for small and medium-sized equipment with double-sided rubber seals, medium load capacity and compact design. Through material upgrades (ceramics/coatings), sealing technology optimization (multi-lip/labyrinth seals) and lubrication strategy innovations (solid/self-lubricating), its application can be significantly expanded to extreme working conditions such as high temperature, corrosion or vacuum, meeting the needs of long bearing life and low maintenance in fields such as intelligent manufacturing and medical technology. When selecting, it is necessary to combine the sealing level, speed limit and cost to achieve the best performance adaptation.

Parameter

Core features

Thin-walled compact design:

Outer diameter 30mm, width 7mm, optimized wall thickness, suitable for small and medium-sized equipment with limited space (such as small motors, robot joints).

The weight is about 12% lighter than that of standard bearings, reducing equipment energy consumption.

Material: high carbon chromium steel (GCr15) or optional stainless steel (SUS304/SUS440C), wear-resistant and corrosion-resistant.

Maintenance strategy

Lubrication cycle:

Relubricate every 2 years in normal environment; once a year in high humidity or dusty environment.

Failure warning:

Check the integrity of the seal ring when the temperature is abnormal (>75°C) or abnormal sound (friction sound).

Replacement standard:

The seal ring needs to be replaced immediately if it is aged and cracked or the bearing clearance increases by more than 50%.
