Round pockets, 31–60 mm
The 31–60 mm range has the most models in the round-pocket series (63), covering common round parts in electronics and precision machining plants: standard deep groove ball bearings (6200–6206 series, typical OD 30–62 mm), rotary encoder housings, round industrial sensor bodies, large-diameter aluminum electrolytic capacitors and round lens module bases. 12–70 pockets, 5–40 mm deep, from shallow to deep sections.
Representative models (selected from 63)
| Model | Pocket (diameter × depth, mm) | Outer size (mm) | Pockets | Typical parts |
|---|---|---|---|---|
| JHTRAC024 | 31 × 6 | 320×208×13 | 50 | Thin bearing covers, round thrust washers |
| JHTRAC025 | 32 × 23 | 300×240×23 | 35 | 6200-series deep groove ball bearings |
| JHHJLP0002 | 34 × 18 | 250×171×20 | 24 | Round industrial sensors, knob housings |
| JHDD0023 | 35 × 5 | 332×245×14 | 35 | Thin optical filters, lens base flanges |
| JHTRAC039 | 48 × 25 | 360×280×30 | 20 | 6204 bearings, rotary encoder housings |
| JHTRAC050 | 58 × 30 | 420×350×35 | 16 | Large deep groove ball bearings, round mechanical parts |
Selection guide for 31–60 mm
| Part type | Pocket diameter | Pocket depth | Notes |
|---|---|---|---|
| Deep groove ball bearings (6200–6206) | Outer ring diameter +1 mm | Bearing width +3 mm | Leave room to pick; a pocket depth equal to bearing width makes removal hard |
| Rotary encoder housings | OD +1–2 mm | Housing height +3 mm | Check whether the shaft protrudes; if so, add depth |
| Large aluminum electrolytic capacitors | Capacitor diameter +1 mm | Capacitor height +3 mm | With leads down, make sure the pocket base does not load the leads; otherwise place upside down |
| Lens bases | Base OD +0.5 mm | Base height +2 mm | Optical parts need tight pocket tolerance to keep surfaces off the wall |
Bearing trays are especially common in this range. To check the pocket size for a specific bearing (6200, 6201, 6202 … 6206), send us the bearing number.
How to size a pocket: measure the maximum OD of the part and add 1 mm for the pocket diameter. For depth, measure the maximum height in the placing direction and add 2–3 mm for picking clearance.
Other round-pocket ranges
