HepcoMotion® ALR
Aluminum Rings for Lighter Load Applications
Rings Weigh Up to 54% Less
than Steel Rings of Comparable Size!
NEW!
KEY FEATURES:
• HepcoMotion ALR aluminum rings run with Bishop-Wisecarver’s DualVee® polymer guide wheels
• Rings are made from anodized aluminum
• Available in 4 standard sizes from 148mm to 300mm in diameter
• Compatible with Size 2 DualVee wheels. For smaller, lighter applications, Size 0 and Size 1 DualVee wheels can be specified
• Guide wheels are comprised of a polymer outer form molded onto a stainless steel bearing and stud
• A cost-effective rotary movement system for medium precision, light load applications
• Suitable for use in applications that require a non-magnetic environment
• Suitable for use in applications requiring corrosion resistance
Data and Dimensions
ALR Rings are machined from high strength aluminum alloy and are anodized which gives an excellent combination of durability and corrosion resistance, and has an attractive finish.
This surface is optimized to run with Bishop-Wisecarver DualVee polymer guide wheels. Stronger DualVee steel wheels will also fit, but their use is not generally recommended due to ring wear. Please contact Bishop-Wisecarver for details.
The four sizes of ring shown below are standard items. Other configurations and sizes are also possible - see page 4.

Motion Without Limits®
DualVee Polymer Overmolded Wheels
Bishop-Wisecarver polymer overmolded wheels with integral studs are perfectly matched for use with ALR Rings.
The outer portion of the wheels are precisely moulded in a high performance engineering plastic which runs smoothly and with little friction or wear on the ring Vees. All metal parts of the wheels are stainless steel.
The bearings in the wheels are shielded, and are lubricated for life internally.
The size 2 wheels (SWIC2P & SWIE2P) are the usual choice for use with all the ALR rings in the standard range shown on page 2, but the smaller size 1 and size 0 wheels will also fit.

For best load capacity and life, it is recommended that the contact points between wheels and ring are lubricated. This can be effected using DualVee Lubricator Assemblies (see page 16 of the full line DualVee catalog available at
www.bwc.com/products/dual-vee.html).
The nominal lives of each wheel at the load capacities stated in the table are 87km, 55km and 41km for the size 2, 1 & 0 wheels respectively.
The system life is determined by the most heavily loaded wheel, and the this can be calculated using the methods detailed in pages 23-24 of the DualVee catalog at the web address above.
The Hepco PRT2 catalog (available at www.bwc.com/products/prt.html) pages 55 to 56 includes calculations which will be helpful in determining the loads on the wheels in an ALR ring based system.
