SEALED BEARING - Protected for superior field performance.

With the introduction of sealed spherical roller bearings, service life in contaminated environments can be significantly increased. Pre-lubricated with a specially formulated grease and sealed with highly effective contact seals, these bearings can in many applications be considered lubricated for the life of the bearing. By eliminating or extending relubrication intervals, sealed SKF spherical roller bearings can significantly reduce the costs to purchase, apply and dispose of grease. Life and reduced maintenance

VIBRATING SCREEN BEARINGS

Vibrating screen equipment in mineral processing has a tough job. The eccentric motion with high vibration coupled with heavy loads puts a strain on components, and especially bearings that are exposed to the elements and abrasive dust. It’s an environment where equipment failure is often accepted as a cost of doing business.

However, specially designed, highly robust solutions can help equipment live with these demands. And help you increase service life and uptime while reducing the costs and safety risks of extra maintenance and repairs.

Explore SKF bearings, seals and lubrication systems for vibrating screens. As well as the SKF Copperhead fault detection system that helps you detect issues and plan maintenance even before they become an issue.

SKF four-row cylindrical roller bearings are available in several designs:

with a cylindrical or tapered bore
open or sealed

Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill applications where the rolling speed is high.

Because four-row cylindrical roller bearings can accommodate only radial loads, they are mounted together with deep groove or angular contact ball bearings, or with tapered roller bearings (either radial or thrust design) which accommodate the axial loads.

The comprehensive SKF induction heater range can be used for efficiently heating bearings and workpieces, both large and small. Their innovative design offers significant advantages to both owners and operators.

Fitting Tools

Help Prevents Premature Bearing Failure.

Poor fitting, usually using brute force, accounts for 16% of premature bearing failures. SKF Bearing Fitting Tool Kits are designed for quick and precise mounting of bearings, while minimising the risk of bearing damage. The right combination of impact ring and sleeve allows effective transmission of mounting force to the bearing ring with the interference fit, minimising the risk of damaging the bearing’s raceways or rolling elements.

Shaft Allignment Tools

Accurate shaft alignment really matters
Reduce machinery breakdowns and increase your uptime

It’s a fact. Shaft misalignment is a major contributor to rotating machinery breakdowns. Accurately aligning shafts can prevent a large number of machinery breakdowns and reduce unplanned downtime that results in a loss of production. In today’s challenging environment of reducing costs and optimising assets, the necessity of accurate shaft alignment is now greater than ever.

Oil Injection Equipment

Mounting bearings using hydraulic techniques

SKF has pioneered the use of hydraulic techniques, such as the SKF Oil Injection Method and the SKF Drive-up Method, for mounting bearings. These techniques have helped to simplify bearing arrangements and facilitate correct and easy mounting.

Dismounting bearings using hydraulic techniques

The SKF hydraulic techniques are often the preferred method for dismounting larger bearings as well as other components. These techniques, which employ hydraulic pumps, nuts and oil injectors, allow the application of substantial forces to dismount bearings or other components. The SKF Oil Injection Method allows bearings and other components with an interference fit to be fitted in a safe, controllable and rapid manner. The method does not require keyways to be machined on the shaft, saving valuable time and money in materials and production. Interference fits have long been recognised for their reliability in transmitting large torsional loads. Very often, interference fitsoffer the only solution when connecting hubs to shafts with intermittent or fluctuating loads.

Mechanical Pullers & Hydraulic Pullers

Choosing the right puller for the job is critical. The puller type, and its maximum withdrawal capacity are crucial for completing any dismounting job safely and easily. Whenever possible, apply the withdrawal force to thering with the interference fit. SKF offers a complete range of easy-to-use mechanical, hydraulic and hydraulically-assisted bearing pullers for use in many bearing applications.

INSTRUMENTS

Temperature

Since the dawn of the industrial age, operators and technicians know that abnormal temperatures often indicate that something is wrong with the machine. Thermometers can help find and then measure these hotspots, allowing further analysis to be conducted.

Speed

Speed Machines are usually designed to run at a given speed. If the speed is too slow or too fast, then the overall process can be compromised. Using a hand-held tachometer enables a quick and easy assessment of the machine’s running speed.

Visual

Visual inspection of a machine’s condition can sometimes be difficult when it’s running or when there is a need to inspect the machine internally. A stroboscope can be used to visually freeze the motion of a machine to allow such things as fan blades, couplings and belt drives to be inspected while running. To inspect the internal parts of a machine often requires disassembly. By using an endoscope, it is possible to access the area of interest with minimal disassembly, saving time and money.

Sound

Sound Abnormal sounds from machines often indicate that something is wrong. A stethoscope can be used to help pinpoint the source of the sound and can aid the technician in identifying the problem. Leaks in compressed air systems are costly, not only in energy costs but also due to extra costs in air compressor maintenance. Ultrasonic leak detectors can help detect leaks efficiently, allowing the necessary repairs to be made. Excessive noise can cause worker fatigue, increased accidents and loss of hearing. A sound pressure meter can measure the sound level, allowing corrective measures to be made.

Electrical Discharge Currents

Electrical discharges are a result of motor shaft voltages discharging to earth through the bearing, causing electrical erosion, lubricant degradation and ultimately bearing failure. An electrical discharge detector can help detect the presence of electrical discharge currents, allowing remedial action to be taken.

Vibration

Abnormal vibrations are often the first indication of a potential machine failure. These vibrations can be caused by such conditions as unbalance, misalignment, looseness of parts, rolling element bearing and gear damage. Vibration analysis instruments and systems, can help detect many serious problems at an early stage, allowing remedial work to be undertaken in a timely manner.

Lubricant Condition

To maintain the optimum condition of rolling element bearings, it is essential that the lubricant is in good condition. Checking the oil or grease condition at regular intervals can reduce downtime and greatly prolong the life of rolling element bearings.
