Mantles, concaves, bronze sleeves, and mainshafts for Telsmith SBS cone crushers — 38 SBS, 44 SBS, 52 SBS, 57 SBS, 68 SBS. Manufactured to original specifications.
Inner Sleeve — Positions and supports the mainshaft. Reduces friction. Transmits power.
Outer Sleeve — Protects the eccentric sleeve. Reduces friction between mating surfaces.
Mainshaft — Connects to the mantle. Transfers rotational force from the eccentric to the crushing surface.
Wear Parts — Mantle and concave/bowl liner. Mn18Cr2, Mn21Cr2. Matching profile sets.
Eccentric and thrust roller bearings create a cam-and-lever crushing action. Large feed opening for bigger feed sizes. Dynamic Adjust system allows CSS changes under load with digital readout.
Maintenance-free hydraulic overload protection. Labyrinth seal + piston ring dual sealing. External locking cylinders — accessible without crusher disassembly. Optional hydraulic anti-spin system.
Models: 38 SBS, 44 SBS, 52 SBS, 57 SBS, 68 SBS.

SBS series allows CSS adjustment while the crusher is running — no need to stop production. A digital readout shows the current setting. This is particularly useful when switching between product sizes on the same material.
Telsmith SBS uses roller bearings instead of bronze bushings. Roller bearings have lower friction and don't require the same oil-circulation system as bushing-type crushers. Bearing life: typically 15,000–25,000 hours with proper lubrication.
Optional on SBS models. Prevents the mantle from spinning backward when the crusher runs empty — this protects the mantle and bowl liner from uneven wear and reduces dust seal damage. Worth specifying if your operation has intermittent feed.
