Frequently Asked Questions about YRT120 YRT Turntable Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, beyond standard ISO specifications, PRS Bearings can produce the YRT120 with tailored radial internal clearances and ultra-precision accuracy classes to meet the strict demands of specialized OEM applications.
The standard YRT120 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 120 mm x 210 mm dimensions without warping.
To maximize the performance of the YRT120, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 120 mm bore. For the 210 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
The PRS Bearings YRT120 features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the YRT Turntable Bearing fits snugly against shaft shoulders, preventing stress concentration at the 120 mm bore interface.
