Cylindrical holding

Loctite ® retaining adhesive for interior space between the increase in shear strength with non-threaded cylindrical member, filling part and cured into a solid precise fit, which is widely accepted as a standard method for press-fitting and Assembly of slip-fit ​​parts. Loctite ® retaining gum with different viscosities, gap-filling ability, good flexibility characteristics, and high strength. Can be automatically or manually glued with process equipment.

Retaining glue for cylindrical parts

603 oil soluble

620 high temperature resistance

l A general-purpose high-strength holding glue with oil solubility and other pollutants. Seal and hold cylindrical parts assembly, its maximum filling radial gap is 0.13mm

l Initial curing within 30 minutes, can prevent fretting wear and crack corrosion between metal mating parts.

l High viscosity, high strength, no flowing. Hold valve sleeve, injection core cover, valve sleeve, cylinder sleeve, keyway, etc.

l It can withstand high temperature to 200 , and provide a shear strength of 19.0N / mm2 or more for steel . Locking and holding the cylindrical fitting to a 0.4mm diameter gap can prevent metal micro-vibration damage and corrosion. Sealed to prevent leaks.

638 high strength

660 fitting repair

l The highest-strength retaining glue can be used to hold shaft holes with a clearance of 0.25mm under dynamic or cyclic loading .

l in 5 early cure within minutes.

l For maintenance, fast curing, large filling gap, high strength, high viscosity (paste). Repair shafts, end covers, keys, keyways, bushings.

l Can repair cymbals. Can restore the correct fit of mating parts, the maximum radial filling gap is 0.5mm

609 low viscosity

641 medium intensity

l High strength, suitable for transition and interference fit. Retaining keys and shafts, bearings, small rotor shafts, bushings, improve the strength of the press fit. Repair damaged holes, shaft fittings or out-of-tolerance parts.

l The most ideal radial filling gap is 0.13mm or less. After 24 hours, it can provide a shear strength of 21mpa . It can easily match parts of different metal materials and can withstand temperatures up to 149 ℃.

l Easy disassembly, used to hold cylindrical fittings, especially suitable for occasions requiring frequent disassembly, suitable for bearing assembly.

l The strength is moderate, and the maximum diameter gap is recommended to be less than 0.25mm to achieve initial curing in 10-30 minutes.

648 high strength / fast curing

680 high strength

l It can be used in occasions where the continuous working temperature reaches 175 , and the filling gap is below 0.15mm . Initial cure in 5 minutes.

l Medium viscosity, suitable for clearance fit or interference fit. Retaining sleeves, pulleys, gears, rotors, repair holes, shaft fittings, out-of-tolerance parts.

l Initial curing within 10 minutes , providing a shear strength of greater than 20.7 N / mm to steel after 24 hours, with a maximum radial filling gap of 0.25 mm
