LINEAR SHAFTING

Case Hardness
PowerTrax™ HG alloy shafting is induction hardened Rc 60-63. Stainless steel shafting is hardened to Rc 50-55. The case depth on all PowerTrax™ HG Shafting is precisely controlled for optimal performance. The extremely hard surface minimizes wear and is resistant to nicks and scratches.

Predrilled & Tapped Holes

PowerTrax™ HG alloy shafting is stocked with radial holes drilled and tapped to accept a continuous shaft support rail. Continuous support prevents shaft deflection when used to support heavy loads or for long travel lengths. Radial holes can be supplied in stainless steel shafts from 1/2" to 2" diameter.

Precision End Machining

PowerTrax™ HG shafting can be supplied pre-machined to application requirements. Send a detailed sketch or blueprint for a prompt quotation.

Shaft Supports

Aluminum support components for end mounting or continuously supporting PowerTrax™ HG shafting.

• Available for inch size 1/2" to 2"

Self-Aligning Pillow Blocks

PowerTrax™ Pillow Blocks simplify mounting of PowerTrax™ Linear Bearings. They are available with EXCEL™ Bearings to fit shafts from 1/4 to 2 inch and 10 to 50mm. PowerTrax™ Pillow Blocks provide or precision bearing bores necessary for linear bearing installation.

Mounting Tolerances

The PowerTrax™ Pillow Block mounting surface to centerline dimension is held to ±0.001 inch. Bearings will self-align up to ±1/2°.

All PowerTrax™ Pillow Blocks are manufactured from precision machined, thick walled, extruded Type 6061-T6 aluminum.

Pillow Block Seals

PowerTrax™ Pillow Blocks are supplied complete with lip seals. The sealed pillow block keeps lubricant in and dirt and debris out resulting in smoother operation and longer bearing life.

LINEAR SLIDE SYSTEMS

Series 100 Slide Systems
PowerTrax™ Series 100 slide systems are pre-assembled and ready to mount. Series 100 slides consist of combinations of PowerTrax™ Linear Ball Bearing Pillow Blocks, HG shafting, carriage plates and shaft supports. Aluminum carriage plates include threaded steel inserts at key mounting locations. All exposed non-wearing components have a protective, corrosion resistant finish.

Series 200 Slide Systems
PowerTrax™ Series 200 slide systems are assembled slides which include:

• Linear bearing pillow blocks
• Integrated end supports
• HG linear shafts
• Carriage Plate
• PowerTrac™ Ball Screw assembly

Many options are available for these slide systems. Different screw styles and leads, protective boots, special motor mounts and custom carriage plate machining is available. Contact Nook Industries, Inc. for assistance.

Mini Slide Systems
owerTrax™ MM Slide™ are metric-dimensioned compact slide units. They utilize lightweight aluminum components and include an integrated carriage/pillow block assembly for a reduced overall height. A wide variety of screw diameters, leads and nut styles are available. These systems include:

• EXCEL™ linear bearings
• Integrated end supports
• HG linear shafts
• Carriage/pillow block assembly
• 1 Lead screw assembly

LINEAR BEARING TYPES

Excel ™ Linear Bearings

Designed to fit into precision bores, these bearings are self aligning and offer long life. Precision hardened and ground bearing plates with ball conforming tracks are contained in a molded thermoplastic housing.

LBB

These bearings are used in lower load applications where self alignment is not required. The precision fit between the bearing and shaft is built into the bearing a result of the solid steel shell. These bearings utilize a molded plastic bearing ball retainer assembled inside a hardened and ground shell.

ILBB Instrument Series

Similar in construction to LBB linear bearings, Instrument Series Linear Bearings are small diameter, high precision bearings with stainless steel shells. When matched with Instrument Series Linear Shafting, ILBB Linear Bearings provide high performance with .0001 to .0003 inch clearances. ILBB Linear Bearings are used in light load, high precision applications where low friction guidance is required such as medical and semiconductor equipment.

Open Series bearings

For applications requiring fully supported shafts, “open” bearings are available in both LBB and EXCEL™ types. In an open bearing, one ball circuit is removed to allow the mounted bearing to translate along a supported shaft.

Seals

LBB and EXCEL™ bearings are available in sealed and unsealed versions. ILBB bearings are unsealed.

Excel™ Maximum Speed

When used in high speed or high impact environments, EXCEL™ bearing capacities should be de-rated as shown in the chart. Divide the rated load by the load factor to determine the appropriate bearing size.
