FUN 32 Metric Series

A pair of flange profile rings separated by a 32 mm ball set; a constant section height of 90 mm and a standard range of external diameters ranging from 1100 mm to 1600 mm

Compared with traditional combination bearing and gearing systems, slewing rings provide a sealed bearing to accommodate axial, radial and moment loads while simultaneously providing a gear for power trasmission as well as bolt holes for fixation.

Key Features

A reduction in the number of design elements
Less component machining
Quick and easy assembly of machinery
Weight savings

Product Overview

A pair of flange profile rings separated by a 32 mm ball set; a constant section height of 90 mm and a standard range of external diameters ranging from 1100 mm to 1600 mm

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 material properties and all stages of production to packing and labelling.

While a flange reduces the overall weight of the bearing, it also reduces its torsional rigidity, and these bearings are thus best suited to light- or medium-duty applications where there is not a high load eccentricity.

What are the Typical Uses for Slewing Rings?

Cranes and crane handling systems
Man lifts and access platforms
Bottling and packing line carousels
Robotics and positioning systems
Solar tracking systems
Wind turbines
Winches
Water treatment plants
Machine tools

Interchange information

The FUN32 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.

Materials

All our QCB^® FUN32 Metric Series slewing rings >1000mm outer diameter will be manufactured in 42CrMo4 steel.

Internal construction

Standard FUN32 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 FUN32 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. FUN32 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 10.9 bolts.The load point should be well under the relevant load curve for long life.

Grade 8.8 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!

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

Typically used in large conveyor systems or ship loaders where the full strength of a solid section, large diameter slewing ring is unnecessary.
