b'LinearMotion LinearMotionLinear Bearings Dimensions - UBCharacteristics Metric Dimensions Used Most Frequently in EuropeHIWIN linear bearings enable high precision linear motion on round shafts by utilizing recirculating ball pathways. UB -* *A UB -* *AJ UB -* *OPThe patented recirculation curve enables HIWINs linear bearing to sustain heavy loads with low noise and high stiffness. ( Standard Closed Type ) ( Clearance Adjustable Type ) ( Open Type )HIWINs diverse line of linear bearings perform under almost any environmental conditions and load capacities to satisfy a wide range of applications.DescriptionJB F L 25 A WWModel Major Dimensions and Tolerance Load CapacityShaftd D L B BasicBasic Diameter Dynamic Staticmm Type Ball Clearance Adjustable Type Ball Open Type Ball mmTolerancem mm Tolerancem mm Tolerancem mm Tolerancem mm mm mm mmRating Ratingd WD1hh1 LoadLoad Standard Closed Circuit Circuit CircuitC(N) Co(N)Type Wiper 8 UB-08A 4 UB- 4 - - 8 16 025 16.5 1.1 15.2 1 - - 280 42008AJ +8 -8Code Description Code Description UB- UB- 012 UB-12A 5 12AJ 5 12OP 4 12 22 32 22.9 1.3 21 1.5 7 54 640 950none No Wiper 0 0 0JB Japanese Spec.
