[Dust-Resistant Double Shields] metal shields on each bearing block workshop dust and metal filings from entering the internal raceway, keeping grease locked in for smooth rolling on 3D printer rails or CNC machine tracks where debris is common. [Precision 90° V-Groove Tracking] Machined to a precise 90-degree angle with 1.4mm groove depth, these wheels grip standard V-rail tracks firmly without side wobble, giving stable movement on linear slides and conveyor guide paths during high-speed operation. [20-Piece Bulk Set for Full System Overhauls] This twenty-bearing pack lets you replace all worn wheels on a linear carriage or slider assembly at once, avoiding mismatched old-and-new rolling resistance across your workshop equipment or automation rig. [Compact 3x12x4mm Size for Tight Chassis] With 3mm inner bore and 12mm outer diameter, these small-profile pulleys fit compact bearing housings and narrow rail channels commonly found in mini lathes, desktop mills, and custom linear actuator builds. [Carbon Steel Build for Repeated Track Cycling] Made from carbon steel with hardened running surfaces, these grooved bearings withstand thousands of back-and-forth passes along aluminium or steel rails without flattening the V-contact zone, ideal for daily-use workshop jigs and test fixtures.
