Tri-roller or roll stake swaging tools have developed as an improvement to the traditional methods of Anvil or 2 wheel swaging. The Tri Roller or Roll Stake swaging tool offers the advantage of allowing the 3 rolling elements in the tool to better contact the V Groove surface of the bearing at the correct angle allowing the V Groove to fold over into the housing.

Precautions Prior to Use
 The bearing must be properly installed and centred in
the housing using an install/remove tool before swaging.
 Ensure the housing has suitable clearance for tool
operation to be performed.
 Make sure all contact surfaces are clean and free of
debris.
 Application of a light machine oil is advised.

Primary Swage
Set-Up Instructions
 Disassemble tool by unscrewing the hex nut (1) on the
locating fixture (2).
 Remove plastic spacer (4) from between the roller fixture
assembly (7) and flip ring (3).
 Place flip ring (3) into locating fixture (2) with the flat side
facing out designated as the primary anvil position.

Figure 5 - Remove plastic spacer from assembly

9. sales@unasisbearings.com Tel: +44 (0) 1235 527 770www.unasisbearings.com
 Insert draw rod (5) into the bore of the bearing until the
rollers (6) are seated on the v-groove of the bearing.
 Align flat on draw rod (5) with matching keyway within
locating fixture (2).
NOTE: ENSURE THE FLIP RING IS IN PRIMARY ANVIL
POSITION.
 Tighten hex nut (1) until the rollers (6) are seated against
the v-groove of the bearing and flip ring (3) is flush against
the housing.
CAUTION: OVER-TIGHTENING CAN CAUSE ROLLERS TO
DENT OR MAKE AN IMPRESSION ON THE V-GROOVE OF
THE BEARING.
 Rotate roller fixture assembly (7) by hand to ensure there
are no restrictions.

Operating Instructions
Step 1 – Tighten Hex Nut
 Tighten hex nut (1) clockwise approximately 30 degrees
causing rollers (6) to apply a small amount of pressure on
v-groove.
NOTE: PRESSURE BETWEEN ROLLERS AND V-GROOVE
SHOULD BE LIGHT ENOUGH TO ALLOW HAND
ROTATION.
Step 2 – Rotate Roller Fixture Assembly
 Rotate roller fixture assembly (7) three complete
revolutions or until it rotates without resistance.
NOTE: A SPANNER CAN BE USED ON TOP OF THE
ROLLER FIXTURE ASSEMBLY TO ASSIST WITH
ROTATING THE ASSEMBLY. ENSURE SPANNER IS
ROTATED CLOCKWISE.
Step 3 – Repeat Steps 1 and 2
 Repeat Step 1 and Step 2 until the hex nut (1) is
rotated approximately 180° or until the v-groove is
completely swaged.
NOTE: A COMPLETE SWAGE IS DEFINED BY A 0.002”-
0.005” GAP OR THE GIVEN MANUFACTURER
SPECIFICATION.
Step 4 - Inspect Swage
Inspect v-groove to ensure the swage is complete and within
specification.
 Inspect bearing to ensure no smearing or galling is
present on the v-groove surface.

Secondary Swage
Set-Up Instructions
 Insert draw rod (5) into the bore of the bearing, on the
opposite side as previously swaged, until the rollers (6)
come into contact with the v-groove of the bearing.
 Rotate flip ring (3) to secondary anvil position.
 Align keyway on draw rod (5) with matching keyway within
locating fixture (2).
NOTE: ENSURE THE FLIP RING IS IN SECONDARY ANVIL
POSITION
 Tighten hex nut (1) until the rollers (6) are seated against
the v-groove of the bearing and flip ring (3) is flush against
the v-groove.
CAUTION: OVER-TIGHTENING CAN CAUSE ROLLERS TO
DENT OR MAKE AN IMPRESSION ON THE V-GROOVE OF
THE BEARING.
 Rotate roller fixture assembly (7) by hand to ensure there
are no restrictions.

Operating Instructions
Step 1 – Tighten Hex Nut
 Tighten hex nut (1) clockwise approximately 30 degrees
causing rollers (6) to apply a small amount of pressure on
v-groove.
NOTE: PRESSURE BETWEEN ROLLERS AND V-GROOVE
SHOULD BE LIGHT ENOUGH TO ALLOW HAND
ROTATION.
Step 2 – Rotate Roller Fixture Assembly
 Rotate roller fixture assembly (7) three complete

NOTE: A SPANNER CAN BE USED ON TOP OF THE
ROLLER FIXTURE ASSEMBLY TO ASSIST WITH
ROTATING THE ASSEMBLY. ENSURE SPANNER IS
ROTATED CLOCKWISE.
Step 3 – Repeat Steps 1 and 2
 Repeat Step 1 and Step 2 until the hex nut (1) is
rotated approximately 180° or until the v-groove is
completely swaged.
NOTE: A COMPLETE SWAGE IS DEFINED BY A 0.002”-
0.005” GAP OR THE GIVEN MANUFACTURER
SPECIFICATION.
Step 4 - Inspect Swage
 Inspect v-groove swage as previously explained to ensure
swage is within manufacture’s specification.
NOTE: REASSEMBLE TOOL IMMEDIATELY AFTER
COMPLETION TO ENSURE NO COMPONENTS ARE
MISPLACED.
NOTE: YOUR BEARING IS NOW FULLY INSTALLED AND
READY FOR INSPECTION TESTS WITH THE USE OF
UNASIS PORTABLE PROOF LOAD TOOL AND UNASIS
BREAKAWAY TORQUE TOOL.
