Decoding the designation

BWU is IKO’s stainless-steel Precision Linear Slide Unit family — a self-contained finite-stroke slide supplied as a matched table and rail rather than as separate carriage and rail items. The 30 is the table width in millimetres and the 45 is the table length in millimetres. Stroke Length: 29 mm.

What these specs mean in practice

Stainless steel throughout the rail, table and rolling elements gives corrosion resistance in wash-down, laboratory and clean-environment service, which is why the BWU range is specified for electronics assembly and precision instrumentation. Balls roll on hardened and ground stainless raceways, so the coefficient of friction is very low and the moving mass is small — a slide with low inertia settles quickly and follows a fast indexing profile without overshoot. Dynamic Load Rating: 1.48 kN. Static Load Rating: 2.2 kN. The unit takes load in four directions and tolerates complex high-torque loading, so a single slide handles side and lifting load as well as downward load. Stroke Length: 29 mm, which is the fixed travel of the assembled unit. Table Width: 30 mm. Table Length: 45 mm — a 30 x 45 mm footprint places this in the compact end of the range where installation space is the constraint.

Quantity and configuration

Unit Quantity: 1 Pc. One complete slide unit: table, rail, balls and retainer as an assembled item.

Interchange guidance

BWU3045 sits in the 25 to 60 mm table-width band of the BWU range. Slides of a different table width or a different table length are a different stroke and a different rating, so the full four-digit size code decides fit. Searchable variants of the number: BWU3045, BWU 3045, BWU30-45, BWU-3045, BWU 30 45.
