Retaining products
Retaining products secure cylindrical parts, bushes and bearings into housings. They increase load transmission capability. Applied as a liquid, they allow 100 % contact between mating metal surfaces.
Key factors which are important for choosing the right product are clearance between parts, temperature resistance , bonding strenght and speed drying.
LOCTITE 603 – high strength, high oil tolerance
- Especially recomended for sintered bearings and also designed for the bonding of cylindrical fitting parts.
Backlash: to 0.1 mm
Required strenght: High
Temperature resistant: -55 to +150°C
Fixture time on steel: 8 min
Packing: 10 ml, 50ml, 250 ml
LOCTITE 620 – high strengt, resistance to high temperature
Designed for the bonding of cylindrical fitting parts.
Backlash: to 0.2 mm
Required strenght: High
Temperature resistant: -55 to +230°C
Fixture time on steel: 80 min
Packing: 50ml, 250 ml
LOCTITE 638 – bonding of cylindrical fitting parts
It is used to metals and deposit materials that reach high temperatures. It also prevents loosening joints and leaks that may occur due to the load.
Backlash: to 0.25 mm
Required Strength: High
Temperature resistance: -55 to +150°C
Fixture time on steel: 4 min
Packing: 10 ml, 50ml, 250 ml
LOCTITE 641 – means for coupling medium strength
It is used for parts, which will be later disassembled (on bearings on the shaft) and prevents loosening joints and leakage.
Backlash: to 0.1 mm
Required Strength: Medium
Temperature resistance: -55 to +150°C
Fixture time steel: 25 min
Packing: 10ml, 50ml, 250 ml
LOCTITE 648 – means high strength
Resistance is lightly contaminated with industrial oils and ideal for hardening of parts with a press fit and resistant to high temperatures.
Backlash: to 0.15 mm
Required Strength: High
Temperature resistance: -55 to +175°C
Fixture time on steel: 3 min
Packing: 10ml, 50ml, 250 ml
LOCTITE 660 – gel of high strength
It is suitable for bonding shim and allowing re-use of worn bearing, dowels, grooves, pins, etc.
Backlash: to 0.5 mm
Required Strength: High
Temperature resistance: -55 to +150°C
Fixture time steel: 15 min
Packing: 50ml
