FAG bearing heaters ensure longer
bearing life
To ensure maximum service life of rolling bearings and steel parts, Schaeffler has developed a range of bearing heaters - to facilitate the mounting of bearings onto shafts
The Schaeffler 'FAG PowerTherm' range of heaters for bearings and ring-shaped metal components, eases mounting work, improves safety and avoids contamination during the heating of work pieces up to 3,000kg in weight The company also offers special induction heating devices for work pieces weighing more than 3,000kg, which are matched to the individual customer power requirements and dimensions

Hand-held condition monitoring system improved
The latest Schaeffler handheld vibration monitoring and balancing device, FAG Detector III, makes condition monitoring easier and more accessible for engineers of all skill levels
Induction heating is superior to traditional methods, being faster, cleaner and ideal for batch heating.
Mobile and fixed heaters and heater plates can be used to heat complete rolling bearings, rings of cylindrical roller or needle roller bearings and labyrinth rings, roll couplings and tyres.
Harmful temperature differences are prevented with uniform heating but non-metallic parts - and the device itself - remain cool.

Bearings for high load / low speed applications
The JK0S range of integral tapered roller bearings are ideally suited to applications in which loads are very high but speeds comparatively low, such as pulleys, crane wheels and cable rollers
During the process, rolling bearing steels are automatically de-magnetised.
Maintenance costs are kept to a minimum using these heater devices.
Due to their increased efficiency, the heaters can reduce heating times by up to 50%.
Also, as the systems do not require oil to operate, they have the added advantage of being both clean and environmentally friendly.
The latest induction heating system for large bearings is the Schaeffler HEATER3000 system.
This is suitable for heating ring-shaped metal work pieces with bore diameters of 285mm over a maximum temperature of 400C.
Due to the high efficiency of the heater (cosine >0.6), the work piece, which can weigh up to 3,000kg, is heated rapidly.
The heater system is an all-steel construction, coated with synthetic resin that is resistant to impact and corrosion.
The vertical ledge is lifted manually or by using a hoist.
The bearing is placed on the support rails and centred, before the vertical ledge is lowered and locked into place.
The work piece can also be pushed onto the horizontal ledge.
The control panel on the heater has clear symbols for different operating modes and so can be operated using work gloves.
The touch keyboard is oil-resistant, dustproof and waterproof.
The basic version of the heater comes with a magnetic temperature sensor, which can be used up to 240C.
Rated voltage is 400V and frequency 50Hz.
Every FAG PowerTherm heater is supplied with a set of protective gloves and magnetic feelers and carries a three-year guarantee.
There are seven other induction-heating devices for mobile and/or fixed use for mounting work pieces up to 1,200kg: Heater 10 is a mobile device used for heating small rolling bearings and other rotationally symmetric parts weighing up to 10kg that have a bore diameter of 15mm + and is ideal for maintenance work in cars and in electrical machines.
Heater 20 is also for small rotationally symmetric parts and bearings but which weigh up to 20kg and have a bore diameter from 10mm upwards.
The heater is a desktop device with a sturdy protective transport cover.
Heater 35 is used for professional mounting work in maintenance workshops and in the production sector.
A ledge makes the device easier to operate and simplifies work.
This heater is suitable for parts of up to 35kg and bore diameters from 15mm upwards.
Heater 150 is a fixed heating device with ledge and work pieces that can be positioned vertically or horizontally.
Parts of up to 150kg and bore diameters of more than 20mm can be heated.
Heater 300 is suitable for very heavy work pieces in a horizontal or vertical position.
This model heats parts of up to 300kg and with bore diameters from 30mm upwards.
A separate trolley with a tray is available for transporting the heating device.
Heater 600 is a fixed heating device with ledge and work pieces that can be positioned vertically or horizontally.
Parts of up to 600kg and bore diameters of more than 145mm can be heated.
Heater 1200 is suitable for very heavy work pieces in a horizontal or vertical position.
This model heats parts of up to 1,200kg and with bore diameters from 215mm upwards.
For heating small rolling bearings and small machine elements such as sealing rings, the PowerTherm Heater.Plate is available.
This device permits temperature adjustment from 50C to 200C.
