Welded steel housings are more robust, typically fabricated or machined steel inserts that are welded into the ends of steel roller tubes. The bearing is either pressed into the welded housing or retained with snap rings or retaining covers.
Very strong and durable
Suitable for heavy-duty or impact-prone environments
Accommodates additional sealing systems (labyrinth or triple-lip)
Designed for standard bearings like 6204-2RS, 6204-ZZ, or insert bearings
Often include a machined bearing seat for proper alignment and tight fit
Mining and quarry conveyors
Aggregate and cement handling
Bulk material handling
Agricultural equipment
