R165119420 Bosch Rexroth KWD-015-FNS-C0-N-1 Linear Runner Block

R165119420 Bosch Rexroth - Product Characteristics

Bosch Rexroth R165119420 is a size 15 ball runner block for the profiled Ball Rail System, with the complete designation KWD-015-FNS-C0-N-1. The FNS format identifies a flanged runner block with normal length and standard height. This exact variant has preload class C0, standard accuracy class N, carbon steel construction, standard SS sealing and no ball chain. The runner block is supplied with initial lubrication and preservation. Dynalub 510 rolling bearing grease is specified for this configuration. Bosch Rexroth also specifies equal high load ratings in all four main directions of loading.

Dimensions

The verified principal dimensions of R165119420 are: Nominal size: 15 A - Runner Block Width: 47 mm B - Runner Block Length: 58.2 mm H1 - Runner Block Height: 19.9 mm H - Assembly Height with Guide Rail: 24 mm B1: 39.2 mm E1: 38 mm E2: 30 mm T - Guide Rail Pitch: 60 mm S2 - Mounting Thread: M5 These dimensions use Bosch Rexroth linear guide nomenclature and should not be interpreted as the d x D x B convention used for conventional rolling bearings.

Runner Block Construction

R165119420 is a recirculating ball runner block designed to operate on a compatible profiled guide rail. The FNS body has a flange-width configuration, normal length and standard height. This version is manufactured from carbon steel and does not incorporate a ball chain. Standard SS seals protect the internal recirculating ball system.

Load Ratings and Operating Principle

The basic dynamic load capacity C is 9860 N and the basic static load rating C0 is 12700 N. Dynamic torsional moment capacity Mt is 95 Nm and static torsional moment capacity Mt0 is 120 Nm. Dynamic longitudinal moment capacity ML is 68 Nm, while static longitudinal moment capacity ML0 is 87 Nm. Bosch Rexroth specifies the dynamic load capacities and load moments on the basis of 100,000 m nominal travel according to DIN ISO 14728-1. The runner block is designed with equal load ratings in all four main directions of loading.

Meaning of KWD-015-FNS-C0-N-1

KWD identifies the ball runner block product configuration. 015 identifies nominal size 15. FNS identifies the format: flange width, normal length and standard height. C0 identifies the preload class: without preload, with clearance. N identifies the standard accuracy class. The complete Bosch Rexroth material number R165119420 and designation KWD-015-FNS-C0-N-1 should be retained when identifying or ordering this exact configuration.

Preload and Accuracy

R165119420 has preload class C0, meaning the runner block is supplied without preload and with internal clearance. Its accuracy class is N, the standard accuracy class for this configuration. These parameters are part of the technical identity of the runner block and should be checked when selecting a replacement rather than relying only on nominal size 15.

Lubrication and Operating Conditions

The runner block is supplied with initial lubrication and preservation using Dynalub 510 rolling bearing grease. Relubrication provisions are incorporated into the runner block configuration. The verified permissible ambient temperature range is -10°C to +80°C, with +100°C permissible for short periods according to the product data. Maximum permissible linear speed is 5 m/s.

Selection and Interchangeability

A size 15 linear runner block from another series or manufacturer should not automatically be considered interchangeable with Bosch Rexroth R165119420. Replacement selection should compare the guide rail system, FNS body geometry, A = 47 mm width, B = 58.2 mm length, H = 24 mm assembly height, mounting dimensions, preload class C0, accuracy class N, sealing configuration and load ratings. Within the applicable Bosch Rexroth system, the manufacturer states that runner blocks and guide rails can be combined across accuracy classes. This statement should not be extended to unrelated linear guide systems from other manufacturers.
