4 ball-bearing smooth-running wheels (2 x fixed, 2 x swivelling) with Ø 125 mm for the TTS 98 PRO, 95 PRO, 93/6 tool trolley, older TTS models and WB 621 and WB 625.
2 of them are equipped with locking brakes to reliably prevent unwanted rolling away.
The hard-wearing rubber rollers are oil, acid, wear and rust resistant.
The thread guard prevents threads from wrapping around the axis and interfering with movement.
The low-noise wheels dampen shocks and vibrations, are gentle on the floor and leave no marks.
