Product Overview
Nine bearings, 250 KG push force, 300 KG tolerance at 25:1, in an 800 g body with a thicker aluminium tube, a stainless steel push rod and a protective dust cap. This is the gun for crews running sealant continuously, and the dust cap is the detail that says who it was designed for.
Key benefits
Why Buyers Choose This Model
Nine Bearings
Nine bearings strategically positioned for efficiency, smoothness and stability. The pack empties more completely and the pull stays light to the end of it.
Protective Dust Cap
A dust cap safeguarding the critical components from dust and debris. On a gun whose advantage is low friction, keeping grit out of the bearings is the whole point.
300 KG Tolerance At 800 g
A 20 percent margin on the highest push force in the nine-bearing pair, and it weighs less than the seven-bearing JS8626.
Hard Alloy Plate And Stainless Rod
A thicker super hard alloy dispensing plate and a corrosion-resistant stainless steel push rod, the two parts that decide whether high force stays usable.
Application scenarios
Where It Is Used
- Continuous all-day professional sealing
- Dusty sites where bearings would otherwise pick up grit
- Structural silicone on curtain wall
- Flagship model of a professional own-brand range
Who it is for
The Buyers This Model Suits
Continuous-Use Crews
Seals all day, every day, and is the only kind of customer for whom nine bearings is the obvious choice.
Dusty Site Contractors
The dust cap is the reason this model survives on a concrete site where an open mechanism would not.
Distributors Building A Flagship
Needs a top of range with a specification list a customer can read and understand.
Problems it solves
What It Fixes
Sealant Left In The Pack
A gun that binds late in a 600 ml pack wastes sealant every pack. Nine bearings keeps it moving to the end.
Grit In The Mechanism
Low friction is only an advantage while the bearings are clean, which is exactly why the dust cap is fitted.
High Force At Acceptable Weight
250 KG in an 800 g gun, lighter than the 880 g seven-bearing model.

Materials and manufacturing
How This Model Is Made
Parts for the JS8634 are produced in our own workshops in Jinli Town, Zhaoqing. This model uses both routes: its moulded components come off our five horizontal and three vertical injection moulding machines, and its metal parts come off our fifteen automatic punching machines, nine automatic lathes and three welding machines. Tooling is designed and cut in our own mould room, which is why a change to this model does not queue behind another factory's schedule.
Quality Control
- Every model is weighed against its declared net weight during production, so the carton weight on your packing list matches what arrives.
- Stamped parts are produced in house on 15 automatic punching machines and 9 automatic lathes, so dimensional consistency is controlled at source rather than inspected on arrival.
- Moulded parts come off 5 horizontal and 3 vertical injection moulding machines running up to 10,000 mould open-and-close cycles per day, with tooling maintained in our own mould room.
- The quality management system was certified to ISO 9001:2015 in August 2023, with a certificate valid to 31 July 2026.
- Cartons are counted against the packing list as they are loaded into the container at our own factory door.
Certifications
The quality management system was certified to ISO 9001:2015 in August 2023, under standard GB/T19001-2016, for the manufacture and sale of glass caulking guns and sealant guns. The certificate on file runs to 31 July 2026; ask us for the current renewal status before relying on it. A TUV Rheinland assessment was obtained in 2016.
Customisation Options
- Aluminium Tube Anodizing And Colouring: More than 10 colours available; the surface can be given a frosted texture.

Use guide
Getting The Best Out Of It
Step 1
Load the 600 ml pack with the rod fully retracted and cut the pack closure.
Step 2
Keep the dust cap fitted; it is the part that protects the bearings the gun is sold on.
Step 3
Work at a steady travel speed rather than increasing grip force, which the bearings have made unnecessary.
Step 4
Use drip prevention at pauses and wipe the stainless rod before sealant cures on it.

How To Read Caulking Gun Force Ratings
Push force, maximum tolerance and drive ratio describe three different things. Confusing them is the most common reason a gun fails in the field.
Cartridge Or Sausage Which Sealant Gun To Stock
Sausage packs cut cost per litre and packaging waste; cartridges are simpler and universally stocked. The right answer depends on who your customer is.
How Many Bearings Does A Sausage Gun Need
Bearing count is the single clearest indicator of duty level on a sausage gun. Three, seven and nine are genuinely different tools.
