• These bearings are an extended inner-ring type and have specially designed set screws with unique thread form.
• The thread form in both series locks the bearing to the shaft so they are resistant to loosening during operation.
• A positive contact, land-riding R-seal provides improved protection against harmful contaminants in both series and retains lubricant under severe operating conditions.
• A 6/6 molded nylon retainer has proved effective under conditions of misalignment.
• YA-RR series has cylindrical outside diameters.
• YA-RRB series has spherical outside diameters for use in housings with corresponding spherical inside surfaces. This provides unrestricted initial self-alignment.
