Bosch Rexroth R165372220 ball runner block, designation KWD-030-FLS-C2-P-1. Size: 30. Format FLS: flange width, long length, standard height. Runner block body: unalloyed carbon steel (CS). Rolling elements: balls in a preloaded O-arrangement. Runs on all Rexroth SNS and SNO ball guide rails, size 30.
KWD: ball runner block, flanged, carbon steel body. 030: size 30. FLS: width flanged, length long, height standard. C2: medium preload class, preload force 3200 N. P: accuracy class Precision. 1: without ball chain, factory-lubricated with Dynalub 510 roller bearing grease.
Dynamic load capacity C: 46,000 N (46.0 kN). Static load rating C0: 66,900 N (66.9 kN). Dynamic torsional moment Mt: 800 Nm. Dynamic longitudinal moment ML: 740 Nm. Static torsional moment Mt0: 1160 Nm. Static longitudinal moment ML0: 1080 Nm. Ratings are equal in all four main loading directions, and they are stated for 100,000 m travel to DIN ISO 14728-1; on a 50,000 m basis multiply C, Mt and ML by 1.26.
Width of runner block: 90 mm. Length of runner block: 119.7 mm. Height of runner block alone: 35.35 mm. Height with guide rail: 42 mm. Rail-to-flange dimensions: A1 45 mm, A2 28 mm, A3 31 mm. Attachment thread: M10. Mounting hole spacing: E1 72 mm, E2 52 mm, E3 44 mm. Guide rail hole pitch T: 80 mm. Weight: 1.560 kg (3.44 lb).
Equal load capacity in all four directions plus C2 medium preload gives enough rigidity to run a single block on a single rail, which halves the rail count on light-load axes. The two extra centre mounting screw holes raise rigidity under lift-off and side loading. Friction coefficient is 0.002 to 0.003 excluding seal drag. The patented entry zone raises travel accuracy by up to a factor of six over a plain entry.
Attachments mount from above or below through the M10 threads. Integrated all-around sealing retains lubricant and excludes contaminants. Permissible ambient temperature: -10 °C to +80 °C, with 100 °C admissible for short periods. Runner blocks and guide rails of any accuracy class combine freely.
One runner block. The guide rail is a separate Rexroth part in the SNS or SNO size 30 range.
KWD-030-FLS-C2-H-1 (R165372320) and KWD-030-FLS-C2-N-1 (R165372420) are the same block in high and normal accuracy classes — related accuracy grades. Searchable forms: R165372220, R-165-372-220, R 165372220, KWD030FLSC2P1, KWD 030 FLS C2 P 1.
