Synthetic expander
(product code suffix: -ER.../-EV...)

The castor is fixed to a level surface using bolts and nuts. The bolt hole spaces are standardised. Plate fittings are available for both swivel and fixed castors and are used for light-duty, transport equipment and heavy-duty castors.
The plate must be aligned with the short side facing in the running direction for castors with a directional lock.

The following dimensions must be taken into consideration when selecting the plate fitting:
• plate size (external dimensions)
• bolt hole spaces
• bolt hole Ø

The castor is attached using a connection element (e.g. a bolt) through the central hole of the swivel head. For levelling castors (series HRIG), the bolt hole has a female thread and the connection element is screwed into the central kingpin of the swivel bracket from the unit side.

The load capacities specified here can only be reached if the top plate lies along the entire diameter of the swivel castor.

This fitting type does not provide positive anti-twist locking, and therefore reduces the load capacity of the swivel head brake.

Using a bolt hole to install the castor is a cost-effective solution, which only requires a single bolt (ideally in compliance with DIN 912 / ISO 4762). This fitting type is primarily used for light-duty and transport equipment castors.

The following dimensions must be taken into consideration when selecting the fitting with a bolt hole:
• plate Ø (external dimensions) (D)
• bolt hole Ø (d)

The castor is fitted using a plug-in stem, which is inserted into a corresponding tube or hole and secured. The stem fitting is fixed to the castor and a fixing bolt (cross hole) or clamp must be used to prevent it rotating or falling out. The hole must be aligned transverse to the running direction for castors with a directional lock.

The load capacities specified here can only be reached if the top plate lies along the entire diameter of the swivel castor.

Stem fittings are primarily used for light-duty, synthetic and transport equipment castors.

A stainless steel plug-in stem fitting is available for stainless steel swivel castors.

The following dimensions must be taken into consideration when selecting the fitting with a stem:
• stem Ø (P)
• stem length (Q)
• position of the cross hole (H), if applicable
• diameter of the cross hole (d), if applicable

The castor is fitted using a threaded pin, which is bolted to the transport equipment using a female thread or a cylindrical hole and nut.

Threaded pin fittings are primarily used for light-duty castors.

A stainless steel threaded pin (-GSX...) is available for corrosion-resistant synthetic swivel castors.

The following dimensions must be taken into consideration when selecting the fixing with a threaded pin:
• threaded pin Ø (thread M10 or M12) (P)
• threaded pin length (protrusion over the castor) (Q)

The castor is fitted using a plug-in pin, which is inserted into a corresponding tube or hole using a synthetic castor socket. The pin is firmly connected with the castor. A spring washer ensures that the swivel castor cannot fall out.

Because this fitting type does not provide an anti-twist lock, a swivel head brake will have no effect.

A plug-in pin is a quick and cost-effective method for fitting the castor to the unit. Plug-in pin fittings are primarily used for light-duty castors.

The following dimensions must be taken into consideration when selecting the fitting with a plug-in pin:
• pin Ø (P)
• pin length (Q)

A synthetic castor socket is an adapter that is used to reduce the internal diameter of tubes to the diameter of the plug-in pin. The synthetic castor socket is pressed or driven into the holder on the unit (round tube). A swivel castor with a plug-in pin is then inserted into the castor socket.

The following dimensions must be considered when selecting a synthetic castor socket:
• internal tube Ø (P)
• pin Ø (d)
• fitting length (Q)
• flange length (B)

The castor is fitted using a metal expander that is inserted into a hole or a square/round tube. The bolt spreads the clamping wedge and presses it against the inner tube wall.
The tightening torque should not exceed 50 Nm. The tightening torque can be reduced to 16 Nm for low-strength thin tubes. A hexagon on the bottom side of the expander prevents the fitting from rotating relative to the castor and coming undone.
Metal expander fittings are used for light-duty and synthetic castors.

The following dimensions must be considered when selecting an expander fitting:
• internal tube dimension (P)
• tube shape (round or square tube)
• fitting length (Q)
• flange length (B)

The castor is fitted using a synthetic expander, which is inserted into a hole or a square/round tube. The bolt presses the synthetic clamping wedge against the inner tube wall.
A synthetic expander provides greater protection for the inside of the tube compared to metal expander fittings. However, it provides less holding force than a metal expander fitting. A hexagon on the bottom side of the expander prevents the fitting from rotating relative to the castor and coming undone.
Synthetic expander fittings are mainly used for light-duty and synthetic castors. A synthetic expander with a corrosion-resistant clamping screw (-EXR.../-EXV...) is also available.

The following dimensions must be considered when selecting an expander fitting:
• internal tube dimension (P)
• tube shape (round or square tube)
• fitting length (Q)
• flange length (B)
