The S61811-2RSR Stainless steel deep groove ball bearings are widely used in fields with stringent requirements for corrosion resistance and cleanliness, such as: food processing equipment (mixers, filling machines), medical devices (surgical instruments, dental handpieces), chemical pumps, marine engineering (ship equipment), pharmaceutical machinery, and semiconductor equipment (cleaning devices).

The S61811-2RSR bearing is a Deep groove ball bearings 2RSR design, self-retaining, Lip seals with an inner diameter of 55 mm , an outer diameter of 72 mm, a width of 9 mm. It typically uses PN grade precision tolerances and GCr15SiMn rings, S = Stainless steel rolling mlement. Its dynamic radial rated load is approximately 7466 N, its static radial rated load is approximately 6458 N. It uses CN standard radial clearance, 2RSR = Lip seals on both sides type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The S61811-2RSR Stainless steel deep groove ball bearings are primarily composed of inner and outer rings made of martensitic stainless steel (such as 440C) or austenitic stainless steel (such as 304, 316), stainless steel balls, and a cage (made of stamped stainless steel or PTFE). They are available in various forms, including open type, with stainless steel dust covers, or rubber seals.

Stainless steel deep groove ball bearings offer excellent corrosion resistance, allowing for long-term operation without rusting in humid, acidic, alkaline, and saltwater environments. They are clean and hygienic, meeting the standards of the food and medical industries. Austenitic stainless steel has non-magnetic properties, making it suitable for precision instruments. The cage can be made of PTFE or self-lubricating materials, enabling lubrication-free operation.
