Q: What’s the advantage of the grease groove in SB204-12G bearing?
A: The built-in grease groove stores and distributes lubricant evenly during operation, reducing friction between raceways and rollers, preventing wear, and extending the bearing’s service life without frequent re-lubriion.
Q: How to install the SB204 pillow block bearing?
A: The pillow block housing features mounting holes for direct fixation on flat surfaces. Simply insert the SB204-12/SB204-12G insert bearing into the housing, align the shaft, and secure with bolts—no complex alignment tools required.
Q: Which equipment is suitable for SB204 pillow block bearings?
A: They’re widely used in low-to-medium speed, heavy-load machinery like conveyor belts, agricultural equipment, mining screens, and food processing conveyors—especially in environments requiring stable mounting and long-term lubriion.
