The 1200K Series self-aligning ball bearings feature a 1:12 tapered bore, allowing easy mounting on tapered shaft seats or with adapter sleeves on plain shafts. The double-row design compensates for up to 3 degrees of misalignment. Tapered bore mounting simplifies installation and removal, making these bearings popular for textile machinery, line shafting applications, and agricultural implement drive shafts requiring frequent maintenance access.
