Flanged Units

Square flange type

UCF***D1
UCF***D1

UCF, UCFU (Set screw type)
UKF, UKFU (Adapter type)
UELF, UELFU (Eccentric collar type)

This square shaped bearing housing can be mounted on the side walls of machinery and similar using four bolts. The construction around the bearing is simple and mounting is easy. This is the most widely used flange type.

C-UCF***D1
C-UCF***D1

C-UCF, CM-UCF (Cast iron covered bearing unit)
C-UKF, CM-UKF (Cast iron covered bearing unit)

A covered unit has a steel plate or cast iron cover mounted on the outside of the bearing housing, making it suitable for locations such as outdoor conveyors that are exposed to rain or high dust levels.

S-UCF***D1
S-UCF***D1

S-UCP, SM-UCP (Steel plate covered bearing unit)
S-UKP, SM-UKP (Steel plate covered bearing unit)

Square flange type with spigot joint

UCFS***D1

UCFS (Set screw type)
UKFS (Adapter type)
UELFS (Eccentric collar type)

This type is for medium loads. It fits into a frame and has a cylindrical spigot joint on the mounting side of a square bearing housing. The unit can be easily mounted so it is suitable for locations subject to a medium load where mounting precision is required. It is used for the main shafts of agitators and similar.

Mounting side

Round flange type with spigot joint

UCFC***D1

UCFC (Set screw type)
UKFC (Adapter type)
UELFC (Eccentric collar type)

This type fits into a frame and has a cylindrical spigot joint on the mounting side of a square bearing housing. It allows accurate positioning with low eccentricity during mounting and is suitable for drum pulleys and similar.

Mounting side

Rhombus flange type

UCFL***D1
UCFL***D1

UCFL, UCFLU (Set screw type)
UKFL, UKFLU (Adapter type)
UELFL, UELFLU (Eccentric collar type)

This bearing housing is rhombus shaped and is designed to enable mounting with two bolts. Multiple bearings can be mounted in a line where space is cramped, making this type suitable for locations such as conveyors where the bearing unit mounting pitch is limited.
A covered unit has a steel plate or cast iron cover mounted on the outside of the bearing housing, making it suitable for outdoor conveyors that are exposed to rain or high dust levels.
The pitch of mounting bolt holes is the same as the diagonal bolt hole pitch of the square flange type bearing, so there is compatibility between the two types.

Light cast iron rhombus flange type

AELFD
AELFD

ASFD (Set screw type)
AELFD (Eccentric collar type)

This unit is more compact than the standard rhombus flange unit, and the notch for securing the bearing is on the front of the bearing housing.

Modified rhombus flange type

UCFA***D1
UCFA***D1

UCFA (Set screw type)
UKFA (Adapter type)
UELFA (Eccentric collar type)

This is a rhombus flange type with a slotted, arc-shaped mounting bolt hole on one side. It is suitable as a tension pulley bearing for conveyor pressure rollers, belts and chains where the shaft center must be adjusted during mounting, or where the shaft center must be moved during use.

Modified flange type

UCFH***D1
UCFH***D1

UCFH (Set screw type)
UKFH (Adapter type)
UELFH (Eccentric collar type)

This bearing housing has all the mounting bolt holes on one side of the housing, so it can be used in the same way as the pillow block type, by mounting in a location such as the side wall of the equipment bed.

Light cast iron rhombus flange type

ASFB
ASFB

ASFB (Set screw type)
AELFB (Eccentric collar type)
CSFB (Tight fit type)

This unit is designed to be even lighter and more compact than a standard rhombus flange type unit, and is suitable for small machinery and locations where the installation space is cramped.
Three types can be configured, by combining with different ball bearings for the unit.

Steel plate round flange type

ASPF
ASPF

ASPF (Set screw type)
AELPF (Eccentric collar type)

The design of this type combines a precision pressed bearing housing made of steel plate with a sealed radial ball bearing. The lightweight unit can be installed where there is little space. The bearing housing can be separated, so it is easily mounted and is suitable primarily for stable light loads, such as shelling machinery. The ASPF2 and ASRPF2 models use the set screw system, and the AELPF2 and AELRPF2 models use the eccentric collar system.

ASRPF
ASRPF

ASRPF (With rubber ring)
AELRPF (With rubber ring)

Vibration absorption capability is provided by combining a bearing surrounded by a rubber ring and a steel plate round flange type bearing housing.

Steel plate rhombus flange type

ASPFL
ASPFL

ASPFL (Set screw type)
AELPFL (Eccentric collar type)

This type is designed with two symmetric mounting bolt holes on the left and right, so like the cast iron type, it requires less mounting space. The bearing housing can be separated, making it easy to handle.

ASRPFL
ASRPFL

ASRPFL (With rubber ring)
AELRPFL (With rubber ring)

Vibration absorbing capability is provided by combining a bearing surrounded by a rubber ring and a steel plate rhombus flange type bearing housing.
