Oil Factory
Linear slides, precision locknuts, support units, rail clamps, felt pinions and locking devices. Stroke to 3900 mm, threads M8 to M200, with standard sizes in stock.
Linear slides in ball screw and belt drive, from 50 to 3900 mm stroke. The KK ball screw slide holds ±0.02 mm across 1050 mm; the LFR belt slide runs to 3900 mm at ±0.05 mm. Supplied as single axes or combined into two and three axis gantries.
Around each linear slide, every part that holds it in position: four locknut series from M8 to M200, fixed and supported side housings in rectangular and flange mounting, rail clamps, lubricating pinions and keyless locking devices.
The axis itself, and everything that holds it in place. Select the component, then confirm the size on its page.
Feed axes and spindles where the preload set at assembly has to survive thermal cycling and vibration without a re-shim in service. BK and BF housings carry shafts from 10 to 40 mm, locknuts to M200 hold the preload without a keyway, and run out is held to 0.005 mm with thread precision to ISO 4H.
One-off machines built to a single part and a fixed cycle time, on short programmes, where every axis component has to come from one catalogue and be on the shelf. Ball screw slides run from 50 to 1050 mm stroke, specified together with their support units and locknuts as one stack, with standard sizes held in stock for short build programmes.
Transfer, loading and pick and place systems, where the axis has to move far and fast, and hold its position when it stops. Belt slides reach 3900 mm stroke at 3000 mm/s unloaded, combine into two and three axis gantries at ±0.05 to ±0.1 mm repeatability, and rail clamps hold 1200 to 2000 N at each stop.
High cycle indexing axes that move thousands of times a shift, where lubrication and holding position decide how long a line runs between services. Rail clamps are rated to 25,000 clamping cycles, felt pinions lubricate rack and pinion drives continuously, and power locks give keyless, zero backlash hub mounting.
Compact, precise and repetitive. Short strokes placing small parts accurately, thousands of times a day, in a confined envelope. Ball screw slides hold ±0.02 mm, compact LMCB slides are available in XY configurations, and single axes combine into multi-axis cells.
A worn support unit or a slack locknut stops a running machine, and what matters is the right size and whether it can ship today. BK, BF, FK and FF units and metric threads from M8 to M200 are held in stock in standard sizes and despatched from Navi Mumbai. Send the part number or a photo and we will identify it.

Every component is inspected before despatch and held in stock against the sizes machine builders need at short notice. Send us the screw diameter and what it is driving.
Ball screw for accuracy and thrust over short stroke; belt for long stroke and speed. The KK ball screw slide holds ±0.02 mm across 50 to 1050 mm of stroke and delivers 376 N of thrust, which suits positioning, measurement and assembly. The LFR 10 belt slide runs from 100 to 3900 mm at up to 3000 mm/s unloaded, at ±0.05 mm, which suits transfer, loading and gantry axes. Very few applications need both in one axis. Those that do are better served by two axes than by one compromise.
It depends on orientation. The KK ball screw slide carries up to 40 kg mounted horizontally and 10 kg mounted vertically. The LFR 10 belt slide carries up to 30 kg horizontally. Send us the payload, the stroke and the mounting orientation and we will confirm the size, since all three decide the selection together.
Repeatability of ±0.05 to ±0.1 mm across one, two and three axis gantries in medium and heavy duty. The figure depends on span, payload and drive type, so it is confirmed against your configuration at quotation.
KMR secures the fixed side support unit to the ball screw shaft, M8 to M56, with a grub screw as the anti-loosening mechanism. KMK covers the widest range, M16 to M200, locking through set screws that draw the threads into contact. KSF locks at three points at 30 degrees on brass threads, M14 to M110, and takes up to 35 Nm, which makes it the safer choice under vibration. KAM covers M12 to M150, and below M15 has two opposed flats so it can be set with a general wrench instead of a special tool.
EN19 throughout, hardened to HRC 28 to 32 and manufactured by high precision turning. Thread precision is ISO 4H, and run out is held to 0.005 mm. The same specification applies across all four series.
BK and BF are rectangular, bolted down through the base, for shafts 10 to 40 mm. FK and FF are flange mounted, for the same function where the housing bolts to a face rather than a bed. The internal arrangement is the same; the choice is decided by how your machine frame is built.
When the carriage has to hold position at a stop without the drive fighting the load. The HZ manual clamping units suit rail sizes 15 to 65 mm, hold 1200 to 2000 N, are rated to 25,000 clamping cycles and operate from minus 10 to plus 70 °C. They are set by lever at 4 to 22 Nm. Typical uses are table transverse positions, carriages and stops.
Most components are made to order, and many standard sizes are frequently in stock. Contact our sales team at sales@drupeengg.com with the part number or size you need, and they will confirm current availability and the dispatch date.
