Frequently Asked Questions
Q: What is the inner diameter of CR 077015?
A: CR 077015 has an inner diameter of 2.952 inches. This dimension specifies the bore size for the bearing cone in Crown electric lift truck steer axle assemblies.
Q: What material is CR 077015 made from?
A: CR 077015 is engineered from hardened alloy bearing steel. The precision machined inner race, roller set, and alloy steel cage provide radial and axial load support in demanding forklift applications.
Q: Where is CR 077015 used on Crown electric lift trucks?
A: CR 077015 is a bearing cone specified for steer axle and wheel assemblies on Crown electric lift trucks. It works as part of a tapered roller bearing set with matching bearing cup components.
Q: How long does CR 077015 last under normal operation?
A: CR 077015 bearing cones typically last 3-5 years depending on load cycles, terrain conditions, and maintenance. Replace when steering feels loose, wheels pull to one side, or bearing noise develops.
Q: What are the consequences of using a damaged CR 077015?
A: A damaged CR 077015 causes excessive wheel play, steering difficulty, accelerated tire wear, and potential wheel lockup. Do not operate a truck with a failed bearing cone; replace immediately to prevent equipment damage and safety hazards.
Q: Does CR 077015 require lubrication?
A: CR 077015 is a precision tapered roller bearing component and relies on proper bearing grease or oil applied to the complete bearing assembly. Ensure the wheel bearing is packed with the correct lubricant during service.
