Frequently Asked Questions
Q: What is a radial ball bearing with an extended inner ring?
A: A radial ball bearing with an extended inner ring is a precision bearing designed to support rotating shafts under radial loads. The extended inner ring allows the bearing to distribute load across a longer surface area, increasing load capacity and stability in material handling equipment applications.
Q: What are the CT 0972188 bearing dimensions?
A: The CT 0972188 radial ball bearing has a bore diameter of 126.165 mm, an outer diameter of 203.2 mm, and an inner ring length of 127 mm. Verify these dimensions match your equipment shaft and housing before ordering.
Q: What equipment does the CT 0972188 bearing fit?
A: The CT 0972188 is designed for Caterpillar electric lift trucks. This bearing is compatible with equipment using the 126.165 mm bore diameter. Cross-reference equivalents exist for Clark and Barrett lift truck models.
Q: Are there cross-reference part numbers for the CT 0972188 bearing?
A: The CT 0972188 cross-references with Clark part numbers 850907, 1302085, 855135, and 908605, as well as Barrett part number CK1302085, and BCA part number 8605. These equivalents fit the same bore and outer diameter specifications. Verify the inner ring length matches your application.
Q: Why would I use a cross-reference bearing instead of the Caterpillar OEM part?
A: Cross-reference bearings from Clark and BCA offer compatibility with the same dimensional specifications as the Caterpillar CT 0972188. These alternatives may provide cost savings or faster availability while maintaining the 126.165 mm bore, 203.2 mm outer diameter, and 127 mm inner ring length required for your lift truck.
Q: How long do bearings typically last before replacement is needed?
A: Bearing lifespan depends on load, speed, lubrication, and operating conditions. Regular greasing and maintenance extend service life. Signs of bearing wear include noise, vibration, increased heat, or roughness during rotation. Replace the bearing if these symptoms develop to prevent equipment downtime and secondary damage.
