Cast Steel Rectangular Housing With Machined Bearing Housing Block and Chamfered Outer Corners

Cast steel grade and bore diameter tolerance together govern fit and fatigue life for a machined bearing housing block with chamfered outer corners; GS-52 grey iron provides adequate compressive strength for standard automotive and oil & gas bearing housings, while GS-42CrMo cast steel is specified for aerospace and shipbuilding applications where cyclic bending at the bolt hole bosses exceeds grey iron fatigue limit. Bore diameter outside H7 tolerance prevents the bearing outer race from seating with the design interference; oversize bore allows the outer race to spin under load and generates fretting fatigue in the bore wall. Dongguan Dalingshan Wangtuo Hardware Products Factory (Dongguan, Guangdong, ISO 9001 certified)(operating as Welltop)CNC-mills this cast steel rectangular machined bearing housing block with chamfered outer corners at their about 4,000 m² Dongguan facility, with bore diameter, housing face parallelism, and bolt hole true position verified to match your drawing during first article review. Supply bore diameter tolerance, face parallelism, bolt hole pattern, and cast steel grade to request pricing from our Dongguan office, serving medical equipment, oil & gas, and drones applications with your enquiry.
