Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, beyond standard ISO specifications, PRS Bearings can produce the PRA042 with tailored radial internal clearances and ultra-precision accuracy classes to meet the strict demands of specialized OEM applications.
Certainly. While the standard PRA042 is pre-filled with high-grade industrial lubricant, PRS Bearings can provide custom fills, including food-grade (NSF H1), high-temperature, or extreme-pressure greases tailored to your operational needs.
Under optimal lubrication conditions, the PRS Bearings PRA042 can reach a limiting speed of 4,440 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
The standard PRA042 from PRS Bearings is heat-stabilized for temperatures up to 120°C. For extreme heat applications, PRS Bearings offers custom S1 or S2 stabilization treatments to ensure the component maintains its 107950 mm x 120.65 mm dimensions without warping.
