Ungeared Slewing Ring Bearing with Single Row Balls (060.20.0744.575.01.1403)
Model No.: 060.20.0744.575.01.1403
Generally, slewing bearings 191.40.2800.990.41.1502 is large-size rolling bearing that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction. Slewing Bearing 191.40.2800.990.41.1502 can perform both slewing (oscillating) movements as well as rotational movements. Basically, 191.40.2800.990.41.1502 consists of an inner ring, an outer ring and rolling elements balls or cylindrical rollers that are separated by polyamide spacers.
The rings, one of which usually incorporates a gear, are provided with holes to accommodate attachment bolts. The holes may be threaded. Generally, only the raceways in the rings are hardened and precision-ground. Integral seals made of crylonitrile-butadiene rubber (NBR) keep the lubricant in, and contaminants out of the bearing. Slewing bearings are relubricated. Slewing bearings through grease fittings to reduce maintenance and operating costs.
Compared to traditional pivot arrangements, slewing bearing arrangements provide many design and performance advantages.
The compactness and large inner diameter simplify the design of the bearing arrangement and its associated components. The low
Sectional height of these bearings means that the pinion lever can be kept short. In most cases only flat surfaces on the associated
Components are needed.
Slewing bearings were originally designed to be mounted only on horizontal support structures, but can now be used successfully
In vertical bearing arrangements. Slewing bearings perform extremely well in a variety of applications such as:
Bucket wheel excavators
Cranes of all types
Small, medium and large excavators
Tunnel boring machines
