SUN 20 Metric Series

Two solid section rings separated by a 20mm ball set, a constant height of 56mm, and a standard range of external diameters ranging from 486mm to 1166mm.

All QCB® slewing rings are manufactured to the highest possible quality levels in ISO certified factories. A QCB® Quality Standard defines all aspects of their dimensions and tolerances as well as all aspects of manufacturing from materials properties, all stages of production, as well as packing and labelling.

Whilst the data on the site is updated regularly, we reserve the right to implement subtle changes to these standards in our quest for continual product improvement.

Applications

  • Industrial positioners (e.g. welding assemblies and jigs)
  • Ship or truck loading chutes and swivels
  • Stretch wrapping machines
  • Conveyors and other materials handling equipment
  • Simple amusement rides

Interchange information

The SUN20 Series is interchangeable with bearings from other manufacturers such as Roth Erde, Torriani Gianni, INA, Schaeffler, SKF, RKS, RIMA, La Leonessa and many more. However there may be variations to this rule (e.g. OEM variants) and we invite you to refer to our technical staff for assistance.

Custom designs

  • Double drilled or custom drilling patterns
  • Higher precision bearings with location diameters
  • Reduced internal clearance (Class 5 & Class 6)
  • Black oxide or zinc plating for enhanced corrosion protection
  • Epoxy paint or even Nylon coated units to special order
  • Stainless steel or aluminium versions

Materials

From 2015 all SUN20 Metric Series slewing rings >1000mm outer diameter will be manufactured in 42CrMo4 steel. Smaller units are usually produced in 50Mn / C45.

Internal construction

Standard SUN20 Series bearings incorporate plastic spacers, but ball spacers, steel or brass spacers, or even full complement and caged designs can be supplied for specific applications.

Seals

A land riding NBR (nitrile rubber) seal strip is standard. VITON seals can be supplied to order.

Gearing

The SUN20 Metric series is ungeared

Lubrication

QCB® Slewing rings are assembled with a small quantity of Lithium EP2 grease. It is important that all slewing rings are greased during installation and prior to operation. SUN20 Metric Series slewing rings will usually have 4 or 6 grease nipples DIN 71412 M8x1 on the radial face of each ring. Sufficient grease nipples for all holes as well as Nylon plugs (to insert if a grease nipple is not required) are supplied with each ring.

Special greases can be supplied on demand as can GreaseMax Automatic Lubricators and Accessories.


Load & Bolt limit curves

If both a radial and an axial load act on the bearing these must be combines into a single equivalent load to enable basic selection from the load curves. The raceway limit is illustrated by the blue line, the red line illustrates the limit for the specified number of Grade 8.8 bolts.The load point should be well under the relevant load curve for long life.

Grade 10.9 bolts can be used but only after approval by our technical team.

Similarly if the load is suspended or the axis of rotation is not vertical please refer the application details to us and take advantage of our decades of experience!
